 Lately i have been making some walkthroughs for this game, and i have givin some
information about some things. But in this i will re-make it all, and add a few more
things to help those in need.

Our first is Keys. In every level there are hidden keys. if you collect all five there is
a special door in the level with locks on it. once you have all five keys in a round go to
that door, and then it will open. inside these doors are special things such as guns,
vehicles, and shorcuts. here i will tell where they all are in order.

Westopolis

-Key 1: The section where you first run into the poisonous red plants will 
bring you to a path with a hole on either side, three Black Arms creatures 
and a zip pad that will shoot you off to the second checkpoint. Jump across 
the hole on the left for an extra life. Across the hole on the right is the 
key.
-Key 2: After the second checkpoint, laser blasts will knock down a couple 
walkways so they sit at a slant. Run up the second one up against the right 
wall and there's a pulley at the end of it. Grab hold to pull yourself up and 
the key is sitting right in front of you.
-Key 3: Drop down and use the zip pad to shoot yourself back down to the 
street. Jump towards the right wall before the slope goes down and use your 
homing attack on the two GUN drones floating there. The key's on the second 
platform. Move fast though or a laser blast will take out the first platform.
-Key 4: Right after the third key is checkpoint number three. Directly to the 
left of this is a gate that you can roll right under. You should already see 
the dumpster ahead of you sparkling. Destroy it to find the key.
-Key 5: Right behind the goal ring is a zip pad that will throw you into 
another fall through some buildings like the start at the level. Immediately 
move yourself in the lower left corner. Be very careful of the helicoptor as 
the blades will hurt you. This may take a couple trips down to get without 
the helicoptor getting in the way. It's easiest to move to the left then move 
down and around the helicoptor at the last second. If you miss, just use the 
last checkpoint to warp back to the fifth one.


Digital Circuit
-Key 1: After the second checkpoint you'll slide down some green poles and 
make your way to a hyperspeed section. Hold right immediately after the first 
firewall on the right side and you'll turn onto a path with they key on it.
-Key 2: After the hyperspeed section, you'll be shot up to a platform with 
three GUN drones. The key is in plain sight right under them. There's even a 
"?" icon next to it to make it easier to find.
-Key 3: After the fourth checkpoint is a set of horizontal poles that move 
upwards. Grab a hold of the left side of the bar farthest to the right and 
ride it up.
-Key 4: Past the fifth checkpoint is a series of spotlights to ride on that 
will take you to different platforms. The third platform (which will have two
GUN drones instead of one like the previous two) has a key on it. Simply let 
the spotlight take you to it.
-Key 5: Passing the Chaos Emerald goal ring and taking the warp portal above 
it will lead you to the final checkpoint. Foreward from that will be a 
spotlight. Use it to travel up, hold up and use your homing attack to make it 
to the far green platform. A bridge of green squares will make a bridge in 
front of you, leading to the key.


Glyphic Canyon
-Key 1: Right after you run into Knuckles you'll reach a wide open space with 
some Black Arms and a staircase behind them. Run to the right of the staircase 
and the key will be behind a small pilliar sticking out of the ground.
-Key 2: Go up the staircase and have the zip pad shoot you off to the next 
part. Run towards the "?" icon and jump up to the platform. It's just low 
enough that you can grab onto it and pull yourself up. The key's resting on 
the ledge.
-Key 3: Continue on until you reach the third checkpoint. In front of you is a 
small staircase with a door directly after it. To either side of this 
staircase is a fence you can smash with your homing attack. Smash the left 
fence to find a key behind it.
-Key 4: Not for quite a while more in the level. Make your way all the way to 
the sixth checkpoint. Run foreward and hit the springs, move move yourself 
backwards towards the camera. You'll land on a green platform with the key 
in the middle.
-Key 5: At the very end of the level, after the last (I believe it's the 
third) tornado ride. You'll be thrown into an area with a lot of Black Arms 
creatures and a staircase in front of you leading to the goal ring. The key's 
to the left of the staircase.


Lethal Highway
-Key 1: Soon after you run into the tank for the first time, part of the road 
will collapse in front of you. Instead of dropping down, look to your right 
and you'll notice a speed pad in front of a small ramp. Use this to shoot 
yourself across the gap. You'll run into the key next to a "?" icon to the 
right side.
-Key 2: After the second checkpoint you'll go inside a tunnel that turns to 
the left. To the left of this room is a wall with sandbags stacked up on it. 
Raise your red gauge by smashing everything and defeating GUN soldiers and 
use Chaos Blast near this wall. A key's right behind it.
-Key 3: Right after that room, you'll run back outside, see a piece of the 
road fall right in front of you, and watch the tank make a pass through the 
area. Jump on top of the road that fell, go left, then backwards. They'll be 
a small section of road with a red flaming car at the end. Destroy the car 
to find a key inside.
-Key 4: Long after the third checkpoint, the road will explode and collapse 
twice. Drop down where the second explosion happened and go backwards as far 
as you can. There's a Black Arms cage way out there with a key in it. Just 
defeat the guards that appear.
-Key 5: Soon after the final checkpoint you'll take a rocket up to a path with 
a rail on it. After you get off the rail, run backwards on the road to find a 
flaming yellow car at the end of the path. Destroy the car and find the key.


Cryptic Castle
-Key 1: Past the checkpoint you'll ride a balloon to the first platform that 
you'll need to use the flames to light the torches. There's a rail on that 
platform. Grind up the rail and go around the left side of the castle pilliar.
-Key 2: After checkpoint five, use the slime trail to make your way to the 
next platform. Then go backwards into the castle. At the end of the path is 
a Black Arms protected cage with a key inside.
-Key 3: After passing the area with the key door, you'll be inside a section 
of the castle with a series of walls you need to break to continue. After 
the first wall, you'll be in a room with some barrels and a couple of wooden 
cabnits. Smash the cabnit on the right side to see a breakable wall behind it.
Smash through the wall and collect your key.
-Key 4: Light the lantern in the room with all the Chao in it to open up a 
path to the left. Go through and reach the section with the Black Hawk. 
Defeat it and take a ride. The key will be under the seventh horizontal 
pilliar on the right side.
-Key 5: Make your way back to the sixth checkpoint and go the route you'd take 
for the normal mission. At the three rail line up before the goal ring where 
the skeleton chases you, when the camera switches in front of you, jump onto 
the left rail. They key's near the end.

Prison Island
-Key 1: Right after the first top secret disc is a "?" icon telling you about 
the panel you can jump on to spring yourself foreward. Jump over the panel 
instead and break the wooden crate. Collect the key inside.
-Key 2: Continue foreward and jump on one of the Air Saucers to start surfing 
down the green slime. Watch out on the left side because partway down they'll 
be a panel you can surf onto. Get onto it and jump to spring yourself up onto 
a platform full of Black Arms. Destroy them all to open up a cage on the same 
platform holding a key.
-Key 3: Run past the third checkpoint and you'll reach an area with a right 
turn with jail cells to the left, followed by a left turn with jail cells on 
the right. You'll know it's the right place because it should be the first 
section of this level you run into the giant worms. There should even be a 
"?" icon nearby. Go to the left turn and look to the left. There will be a 
small room inside of the wall with a wooden crate in it. Smash the crate and 
find the key inside.
-Key 4: Another platform surfing section after the forth checkpoint will bring 
you down a slope to see a large section to the right with some GUN mechs on 
it. Get onto the platform and make your way to the far right side. In the 
corner is a wooden and a metal crate, but just in front of it is a giant slab 
on the ground. Press X in front of the slab to flip it over, revealing a key 
below it.
-Key 5: Triangle jump above the goal ring to move past it and to the sixth 
checkpoint. Another surfing section is up ahead. Make your way down the steep 
slope avoiding all the junk in the way. At the end of it is a platform 
extending out of the middle. Surf down the slime to the right of this 
platform and grind down the rail. Use the platform's double jump at the end 
of the rail to grab the key floating there.


Circus Park
-Key 1: Right in front of the second checkpoint is a path that branches off to 
the left and the right. Jump between them off the platform and use your homing 
attack on the blue ball in the middle. It will bounce you up and into the key.
-Key 2: Behind the third checkpoint. Grab it and go backwards as far as you 
can on the platform below it. There's a key in the Eggman crate.
-Key 3: Right after the fifth checkpoint is a rope you grind down that leads 
to a platform with a rocket on the top section and two GUN drones down below. 
Behind the drones on the far end of the platform is a key.
-Key 4: After taking the rocket and parachuting down, you'll wind up in front 
of another triangle jump section. Drop down and look behind you to see a 
series of barrels to jump across with a key on top of the last one.
-Key 5: After the circus tent you'll end up at a zip line ride. Get on and 
hold left and you'll eventually run into the key.

Central City
-Key 1: Go right at the start of the level. Pick up the bomb in front of you 
and throw it foreward into the wall. Hit the springs that appear there, go 
up, and hit the first checkpoint. Detonate the first big bomb there and go 
up the platform and tilts over. In the section right before the area you 
triangle jump across, a helicoptor will come down. Grab a hold of it and 
have it lift you onto the roof. Destroy the two Black Arms soldiers that 
appear on the roof and collect the key in the cage.
-Key 2: To the left of the third checkpoint is a big wall of sandbags with a 
"?" icon next to it. Build up your dark gauge (destroying the GUN mechs 
around the large bomb nearby should be enough) and use Chaos Blast near the 
wall to destroy it. There's a key behind the wall.
-Key 3: Destroy the wall next to the fourth large bomb and climb up the pole 
to reach the fourth checkpoint. Destroy the Black Arms in the area (there 
should be a soldier, a giant, and two Black Hawks) and a cage will open up 
with a spring. The spring will launch you up onto a platform which you can 
use to jump to another platform on the other side of the street with a key 
on this. Two notes for this key - 1: If you're using the turret to take out 
the Black Arms, be careful not to destroy the platforms on the side of the 
buildings. 2: If you're lucky, you can use your homing attack off of the 
Black Arms to climb your way up to the key without having to unlock the 
spring.
-Key 4: Destroying the two GUN mechs around the final large bomb will not 
only open the cage holding the bomb, but open a cage near it next to the 
building with a key in it. Just go to the building right of the bomb and 
turn around.
-Key 5: Follow the road, passing the final checkpoint just a bit, and keep 
your eyes open on the left wall. One of the buildings will sparkle a bit. 
Shoot it with a rocket launcher (take one from a GUN mech earlier on in the 
level, there's some near the third large bomb that have the weapon) and 
collect the key behind the wall. Note, Chaos Blast will NOT work on this 
wall.


The Doom
-Key 1: Near the very start of the level. Run into the second room and 
trigger the elevator in it. Ride it to the top and wait for it to lower so 
you can hop on the top of it. The key should be hovering above the platform 
next to the elevator.
-Key 2: Keep going until you reach the room with a huge slope. It's the room 
that starts off with a big slab on the floor and a GUN mech right behind it. 
Run about halfway up the slope and rev up a spindash. Jump when you get about 
three-forths up the slope and you should fly up into the air. Right above the 
middle of the room are two platforms: One has an extra life, the other has a 
key.
-Key 3: In the same room there should be a bomb regenerator at the end. 
Normally you'd throw a bomb at the wall ahead of you to the left of this 
thing, but turn to your right and you should see another cracked wall. Throw 
the bomb at it, the third key's just inside.
-Key 4: A few rooms ahead is a three way split room. There will be a fan 
blowing on the right side of the split and a dead end with a couple GUN 
soldiers and crates in it. Jump on the pilliar in the left corner and turn 
around. You should see a pulley that you can jump onto. Have it pull you up 
and jump off onto the platform with an extra life on it. Turn towards the 
fan and there should be the key floating right above it.
-Key 5: A few more rooms ahead and you should be in an area with a cage in 
the middle that has a single ring in it. Use the elevators to get to the top 
of the room and keep moving foreward through the rooms. You'll eventually 
reach a room where GUN soldiers burst out of the walls. In the far right 
corner of this room are some GUN crates stacked up. Jump on top of these and 
you can reach a platform above. Look towards the wall to see more GUN crates 
stacked up against it. Smash them and collect the last key behind the wall.


Sky Troops
-Key 1: After the tail of rings used for the light speed dash, you'll find 
the GUN jump mech and hop up some platforms that will eventually lead to a 
large slope with some pilliars rolling down it. Before going up the slope, 
stand in front of it and look to your left. The key's right behind the 
doorway you ran through.
-Key 2: Right after the third checkpoint, make your way past the room with 
the second crystal and through the loop until you hit the zip pad that brings 
you to the next section. Run up the staircase leading to the open area and 
look to your left.
-Key 3: Soon after the fourth checkpoint, the path will branch off into two 
paths. Run down the right side until the slope stops. The first Black Arms 
creature should actually be staring right at the key. It's in plain sight to 
the left on the wooden platform just before the large mounted cannon.
-Key 4: Running foreward some more will get you to a section that will have 
two zip pads and a switch next to them. The switch triggers a trail of rings 
that leads to a zip ring that will push you onto a platform with a mounted 
cannon. The key's sitting right next to the cannon on the right side, again 
in plain sight.
-Key 5: After checkpoint six, you'll take a ride on a Black Hawk. About 
midway through the ride you'll fly through a giant tunnel. Jump off here and 
make your way to the end of the tunnel back where the weather's sunny again. 
There's two platforms under you just out of sight, so be careful when you 
jump down to land on them. One platform has a rocket to take you to the final 
area. The platform in back of it has the final key. 

Mad Matrix
-Key 1: There's a blue platform between the blue and green terminals that has 
a key on it. Take the right path when you first get to the section that 
splits the level up. 
-Key 2: In the yellow terminal. There's a section with a color puzzle wrapped 
around a square platform. Solve the puzzle and move to the left side of the 
puzzle. When it raises, it will pass a key.
-Key 3: In the green terminal. After checkpoint five you'll go through a 
couple moving platform sections. At one point there will be a color puzzle 
with two panels vertically stacked, a red one and a green one. The key is 
directly behind these panels. Move fast to get it.
-Key 4: In the red terminal. Right in front of the first color puzzle, 
there's two platforms on the left and right sides and a key between them. 
Jump onto one of these platforms and wait for a purple cube to float by and 
under the key.
-Key 5: Way past the goal ring floating out in the middle of nowhere. Just 
keep going straight towards the purple cube in the distance.


Death Ruins
-Key 1: The first pulley will take you to a platform with two GUN soldiers, 
two Black Arms soldiers, and a spring which will bounce you into some elastic 
substance that will shoot you off to the second checkpoint. When the elastic 
stretches back, jump to get yourself out of it and onto a platform with a key 
on it.
-Key 2: After the third checkpoint is a rail section that will wrap around a 
large pilliar with some platforms on it. Get onto the first platform you can. 
This platform should have three GUN soldiers on it with a GUN cage that has a 
shield inside. In the far left corner of this platform is a pole below the 
platform you can slide down onto another small platform with a spring. The 
spring will take you to a second rail. You can see several gray platforms 
near the base of the wall that this rail takes you down. It can be hard to 
find a good section of the rail to jump off to get to one of the platforms 
on the side of this wall and work your way down, so instead try jumping off 
the rail early and falling down to one of these gray platforms. One of the 
lower ones has a key on it. The lowest one will move up when jumped on to get 
you back up.
-Key 3: Checkpoint five will lead you up a small water section. After getting 
up that you'll be on a path with a cage blocking the left side. The right 
side has a small hole in the ground with a red slime path starting point and 
a spring behind it. Just to the right of this is a wall you can destroy to 
reveal a small ledge with a key on it.
-Key 4:After checkpoint six, you'll find a red slime path to the right. Ride 
on it to wind up in a room with a triangle jump section in front of you. The 
trick to this key is getting high enough up the wall to get the key. Jump on 
top of the wooden gun crate and start your triangle jump by jumping onto the 
wall from here. This should give you enough height to grab the key near the 
end of the hallway.
-Key 5: Past this key is a door that will lead you to a room with a vertical 
pole. Slide down the pole and get into the next room. There should be a Black 
Arms Cage and a large platform in front of you. To either side of the large 
platform is a small path with a Black Arms soldier and a breakable wall at 
the end of it. Break the wall and peak around the corner to see a key behind 
a small waterfall.


The Ark
-Key 1: Right behind you from the start. How 'bout that? I'm sure you knew at 
least one level would pull this trick on you.
-Key 2: After the third checkpoint, you'll fly down through part of the ARK, 
then wind up near a series of platforms with giant defense turrets on them. 
Jump down onto the platforms and make your way down them. The second to 
lowest platform has two lines of rings under it and a key at the end of the 
ring lines hiding under the third platform.
-Key 3: After the fourth checkpoint you'll fly through a small tunnel with 
flashing yellow lights running through it. After getting out of the tunnel, 
watch the lower part of the screen very carefully and you'll make out a 
platform in the distance. Wait until you're close to the wall and jump off 
the Black Hawk to land on the platform. There's two gun crates and a key on 
it.
-Key 4: After the fifth checkpoint, fly foreward until you see a platform 
with a tunnel below you. Jump onto the top of the tunnel and drop down to get 
inside it. The key's at the close end of the tunnel.
-Key 5: Past the goal ring, just run down the tunnel.

Air Fleet
Key 1: First triangle jump oppertunity. Avoid the lasers and get to the door 
at the end to find the key behind it.
Key 2: When you reach the section that splits the path up into two ways, 
take the right path. Keep an eye out for a large brown container with a 
wooden crate on top of it. The crate has a key inside.
Key 3: Soon after the first outside section of the level, you'll wind up in 
a huge circular room. Go to the right side of the room and travel up the red 
slime. Move around the walkway to find the key between two roadblocks.
Key 4: Another fork in the road after the fourth checkpoint. Go right again. 
You'll soon find a gun turret. The key's in a crate to the left of it.
Key 5: After the seventh checkpoint, you'll find another large circular room. 
Go left and up the red slime path to get to the walkway. Run around and 
you'll find the last key between two large brown containers.

Iron Jungle
-Key 1: Right after the third checkpoint is a left turn. Look to the left 
to see a GUN drone floating in front of a small room. Use your homing attack 
on the drone to get up into the room and smash the cases on the platform to 
find a key behind them.
-Key 2: After the fourth checkpoint is another one of those rooms you drop 
into with three Shadow drones in it. Defeating the Shadow drones will raise 
the platform in the middle up so you can get out. Jump into the room and 
turn around. There's a door behind you that has some crates and a key behind 
it.
-Key 3: Take the lower route after checkpoint five, grinding down the rail. 
It will lead you to another checkpoint and drop you into a room with three 
more Shadow Androids. Turn around and the key's in some red cases behind you.
-Key 4: This one takes some backtracking. Use a further checkpoint to get 
back to checkpoint five, only this time, take the upper route. It will 
eventually lead you to a checkpoint and a vertical bar you can climb down 
into a room with a GUN mech in it. Destroying the mech will open the cage to 
reveal a spring to get out of the room. Right behind the caged spring is a 
platform just out of view of the camera. Run to the edge and rotate the 
camera to see the platform and the key.
-Key 5: Right next to the goal ring, behind those red barrels on the left.

Space Gadget
NOTE: This level seems to be a real odd one for key finding. Note that some 
of these keys are more difficult to get then most other levels and getting 
some of them require methods that probably aren't the ones Sonic Team 
intended. At least it seems that way. 

-Key 1: After the first checkpoint you'll get to a slope with a gravity 
switching device at the end. Switch gravity and it will take you down to 
another slope. Instead of going down, use your spin dash to get speed, then 
jump across to the platform above. Go down this slope instead to see a key 
at the end by the speed pads. Be very careful of the speed pads though, 
because they'll boost you in the opposite direction, away from the key.
-Key 2: You should notice this one on top of a platform directly before the 
second checkpoint. When you hit the checkpoint, turn around. Notice the 
light sticking out of the side of the platform? You're going to have to 
bounce off of that. This isn't easy at all and will probably take a few 
tries to get right.  Jump on top of one of the lights on the ground nearby, 
then jump as high as you can and use your homing attack to dash towards the 
light on the side of the platform. If you're lucky, you'll bounce up high 
enough to get onto the platform with the key. If the light breaks and you 
aren't up there, just jump off the side, lose a life and try again.

NOTE: SHADOW JACKY has played through Expert Mode and says the platforms are 
rearranged in this section of the level, making it much easier to get this 
key. Unfortunately, he also claims gaining keys won't save while in Expert 
Mode. I've yet to unlock this, so I can't say for myself.

-Key 3: Take the dark path foreward, destroying the second defense unit and 
dropping down the hole where the panels used to be just before the second 
checkpoint. Keep moving foreward until you reach the next checkpoint (the 
sixth one) This is where the level starts to get pretty confusing, especially 
if you're looking for keys. Make your way into the room with the fourth 
defense unit (one of the rooms that shoots lasers from three circles on the 
ground) Make sure the room's right side up and the gravity's normal. If it 
isn't, there should be a gravity switch somewhere in the room that fixes it. 
Jump onto the defense panels and look at the wall behind the defense unit. 
A key's hidden in the right corner. Just jump off the defense panels and use 
your homing attack to make it up there.
-Key 4: After the last checkpoint, go into the next room, fall straight down, 
use the springs on the other end to get back up. Then, go right to find 
another spring. Use it to get up to a beam. Run to the right of the beam. 
Spindash at an angle near where the beam connects to the wall, and use this 
section as a ramp to get enough height to jump over to the beam in front of 
you. The key is lying on the middle of this beam.
-Key 5: You're going to need to warp back to the normal path, either by using 
a checkpoint or the warp portal at the end of the dark path. Look above the 
goal ring. The key's floating there just out of reach. That means you have to 
go all the way through the normal path, then at the section where gravity 
switches, putting you onto a rail that winds around and takes you to the 
platform with the goal ring, you're going to need to jump off instead and 
fall towards the ring. This part's tricky because you need to aim it just 
right, weaving between the meteors near the end of your fall. If you're 
lucky, you'll fall just on top of the key. If not, go to the fifth 
checkpoint and try again.

Lost Impact
-Key 1: Get to the first room with the elevator section going up. Head 
upwards until you finish riding the last elevator. Look off the ledge to see 
a vertical pole. Jump off the ledge and grab onto the pole, climbing up to 
the top of it to find a key.
-Key 2: After the second gun rail line section, go through the right door on 
the right wall. The room will have a zip pad that will lead you into a series 
of springs that takes you up to a small room with a couple wooden gun crates. 
Jump on top of one of the pilliars in the back of the room and jump to the 
other. The key's floating up in the air between them.
-Key 3: After the fifth checkpoint you'll ride a gun rail line out to meteor 
field. Stop the gun right when you get outside and look to your right to see 
a platform with a rocket on it. Ride the rocket up to a platform with a key.
-Key 4: In the room with the last checkpoint, above the gun rail line doorway 
you can in from. Go up the platform to the right, get on the ledge and jump 
up to to platform to grab a hold of it and pull yourself up.
-Key 5: Make sure you have an explosive weapon ready. Go through the door 
closest to this key (the right door on the right wall) and you'll run into a 
wall with a crack in it. Shoot it with a rocket to blow the hole open, 
revealing an extra life, a ring box and the last key.

GUN Fortress
-Key 1: The very first room of the level, behind one of the big brown 
containers near the GUN soldiers and Black Arms soldiers.
-Key 2: In the room where you use the turret to destroy two GUN mechs to open 
up the cage in the center. The cage will let you use the zip line to get to 
the walkway surrounding the room. When you get off the zipline, go right. 
It's between a couple of those big brown containers, almost in plain sight.
-Key 3: Keep going until you get to the next big room similar to the one the 
last key was in. When you get on the walkway surrounding the room, you'll 
run left until you find a pulley. Instead of using the pulley, run past it. 
There's a key at the end of the path.
-Key 4: After the fourth checkpoint the path will split, giving you the 
option to go up a pulley, or straight through a door. Go through the door 
and get to the second mainframe computer (those big blue ones you need to 
destroy for the dark mission). The key's right behind the computer, 
surrounded by roadblocks.
-Key 5: Right after the five key door is a narrow room with trapped walls. 
Triangle jump between the walls before they close in on you and make it to 
the end to find an extra life and the last key.


Black Comet
-Key 1: At the start of the level, wind your way up the platforms instead of 
going straight through the poison fluid stream. Defeat both GUN mechs so the 
platform to the left of the room rises. Follow the path it leads you to and 
go down the red slime stream. Go across the bridge to your left and look 
behind the rocks at the very end.
-Key 2: Hop on an Air Saucer next to the second checkpoint and move along the 
right wall. There's a small path hidden around the far right that will lead 
you to the second key.
-Key 3: The sixth checkpoint is in a large room that will have you spiraling 
down platforms and rails. Get to the bottom of this room and through the 
hallway into the next. When you get into the new room, look to the left. 
There's a key just sitting there.
-Key 4: This one isn't even hidden. It's in plain view of the main path. Go 
foreward two rooms from checkpoint seven and you'll be in a room where you 
drop down to fight two worms. Instead of dropping down, you'll see a soldier 
appear in front of you to the right a little bit. The key's behind him, by 
the panel on the wall with the glowing red outline. You should see it 
sparkling already.
-Key 5: In back of the goal ring. Use one of the air saucers to jump into the 
poison liquid.  The key's behind one of the tentacles close to the last 
checkpoint.

Lava Shelter
Key 1: Right after the first checkpoint, triangle jump between the walls 
until you reach the door at the end. A key will be behind it.
Key 2: After another rail section you'll go through a small hallway with a 
couple of lasers and into a room with a pulley in the middle. Ride up the 
pulley and go through the door to get into the next hallway. Early in the 
hall is a grating on the ground you can pick up and flip over. Drop down 
into the path it makes and go down the slope to find a key.
Key 3: Grind the rail after the third checkpoint and it will lead you to a 
narrow hallway. Triangle jump between the walls until you reach the door at 
the end. A key will be behind it.
Key 4: Soon after the huge room with the rail spiriling down, you'll reach a 
section where the rail will split into three. Quickly jump to the right rail.
Key 5: Use the final checkpoint to backtrack to checkpoint number four. 
Activate the lava defense system inside the room ahead and use the newly 
made platforms to make your way to checkpoint number five. Continue on 
through the level, activating one more lava defense system. After scaling 
your way up this huge room, you'll eventually get to a door and the key will 
be right in front of you.

Cosmic Fall
-Key 1: Make your way past the first checkpoint until you reach the zipline 
section. Ride on it and hold left. The key's about halfway down the rail.
-Key 2: After the third checkpoint, you'll cross some falling platforms until 
you reach the one at the end with a trail of rings that goes up. The platform 
will slowly rise up this trail of rings. A key will pass by near the upper 
right section of the platform. It might be a bit hard to grab with the camera 
angle.
-Key 3: After the fourth checkpoint, there will be some platforms rotating in 
place in front of you. Make it across these series of platforms to the last 
one without falling to find the key.
-Key 4: Pass the goal ring and use the zipline to bring yourself to the sixth 
checkpoint. Get on the jumping mech and jump up the platforms to get to a 
series of pulleys. Let them take you up to a platform with an Artificial 
Chaos and a few crates. Go right after getting on this platform to see a 
rotating platform with a key on it. Be careful getting this one, this can be 
a tricky key.
-Key 5: Keep working your way through to the computer room until you reach a 
series of platforms with zip pads that throw you high up into the level. 
You'll spend quite a while falling at the end of this. Use this time to aim 
yourself near the top right of the platform you're falling down to. The 
closer you get, the more you can make out a key on the very top of a pilliar 
on the right side of the platform. Land on the pilliar and get your key.


Final Haunt
-Key 1: After the second checkpoint, run foreward and defeat the two elite 
Black Arms soldiers. Then, run behind the platform the checkpoint was on to 
see a Black Arms cage lowered with a key in it.
-Key 2: Run past the third checkpoint, through a couple loops, and into a 
room with a few Black Arms giants. There's a slope on the right side of this 
room. Run up it and destroy any rocks in your way. There's a key sitting 
right up there.
-Key 3: After checkpoint four is a room with a few Black Arm elites. 
Defeating them will open up two cages; one with a spring and one with a 
vacuum gun. Run past the cage with the vacuum gun and up to the wall, then 
look to the right. You'll see a key at the end of the hallway.
-Key 4: At the end of the room with the key doors (a way after the fifth 
checkpoint, you'll know when you get there) you'll follow a light speed ring 
trail that will take you up and out of the room. The next room will have a 
platform on either side, and a lower platform in the middle that leads to a 
rail into the next section. Use the platforms at the end of the rail you're 
on to jump over to the other side where a few elite Black Arms troops are. 
Take them out and run to the end of the platform to find the key.
-Key 5: Now warp back to checkpoint four and trigger the switch, opening the 
path in front of you. Tame and fly on the Black Hawk unti it drops you off in 
front of the door. Go back into the middle section and take the path on the 
right. There's a key sitting just in the middle of the end of the path.

The Last Way
-Key 1: The room after the first Black Arms battleship has a giant and a red 
slime path on the wall. Jump down to the left and take out the two worms to 
lower the cage. There's a key inside.
-Key 2: The first Black Hawk flight drops you off on a bridge between two 
paths. Run toward the end of the left path instead of the right. There's a 
key in the corner.
-Key 3: After the large circular room with rails spiriling down it, you'll be 
dropped off into a room that has some Black Arms soldiers shooting you from 
floating platforms. Get on these platforms and use them to jump over to the 
path on the left, where there's a key near the far wall.
-Key 4: This is easily the hardest key to get in the level, and your timing 
with Chaos Control is going to have to be pretty good. After the fourth 
checkpoint, you'll be forced to use Chaos Control to get through a couple 
rooms. The second instance, you'll be in a long path full of worms. The end 
of the path has a door at the top right that you can't get to without Chaos 
Control. Fill up your blue gauge and run back a bit from the end of the path 
(run back until the end of the path is just barely out of sight) Now wait 
for the blue gauge to almost empty out completely and use Chaos Control when 
it's almost gone. If you're lucky, you'll have just enough to get to about 
the door and stop in front of it. If you skip the door and wind up in the 
middle, lower path of the next section, you're going to have to go back and 
try again. You should be on the right side of the room and at the end of the 
path, you'll see some Black Hawks you can use your homing attack on to get 
across to the left. Jump over to the left side and defeat the Black Arms 
soldiers to lower the cage and grab the key.
-Key 5: The room with the fourth key is also the same room that has the fourth 
checkpoint. Continue from there, going through a couple loops and you'll end 
up in a room with three Black Arms giants. Make your way up the platforms on 
the right then when you turn left, keep going foreward instead of using the 
zip pads. Defeat the giant at the end and collect the key in the cage it 
opens up.

The next thing i have to talk about is two levels that I'm always being asked about is two
levels that people are ALWAYS having trouble with. The first one is the one with all the
artificial chaos. Here is my guid to find them all i put in order so you don't have to
decide which one is where in the level. Soon after you do it about five times i can almost
100% sure that you wont have to use my guid anymore.

1 - Right at the beginning, you'll use a spring to get across a red-lit pit, 
and the first will be in that room.

2 - Keep going through the hallway, through the various doors and rolling 
under the wall, and you will reach the first Gun Lift room (as I will call 
them from now on.  They are characterized by the green 
liquid pits, the Gun Lift Turrets you can ride start in them,  and they 
usually (not always!) have a Save Point in them.).  The second will be right 
after the first Save Point.  

3 - Go up the lift on the opposite side of the Save Point in the Gun Lift 
room.  Then go up the other one.  The third is up here, alongside a Beetle 
sentinel and a GUN soldier.  

4 - Go up the lift.  Go through several doors, including one with a bomb 
in the room, and you'll find AC number 4.

5 - Go back down to the Gun Lift room and hop into the Gun Lift turret.  
As you coast along this green rail, number 5 will be dead ahead.  

6 - Keep going a little more, and number 6 will be near the end of this 
turret ride.

7 - As you arrive in Gun Lift room #2 as the turret ride ends, number 7 
will be in this room right in front of you.

8 - Right next to number 7.  Hit the Save Point in here.

9 - Hop into the turret.  As you go out in space, AC number 9 will be 
there.  

10 - Number 10 will near the end of this turret ride.

11 - Next to number 10.

12 - This AC will be inside Gun Lift room #3 as you end this turret ride, 
right in front of you.  Hit the Save Point here.  

13 - Go up the lift right next to the Save Point.  Then, go up another one.  
Hit the spring and as you climb up the pole, destroy AC number 13.  

14 - Either keep climbing up the pole, or go back down and take the lift 
up one level.  Number 14 is there, alongside some GUN soldiers.

15 - Next to number 14.

16 - Go all the way back down to the first level of Gun Lift room #3.  Go 
through the left door on the opposite side of the Save Point, and you'll 
reach a fork in the road with rings on the left path.  Take the right path.  
Go down this path, and you'll reach a room with another red-lit pit (it 
will be on the left side of the room, and this is one AC people often miss).  
Destroy the AC hovering over the pit.

17 - Go back to the fork and this time, take the left path.  Keep going and 
you'll see some GUN soldiers shooting through a hole in the wall.  Number 17 
will be there.  

18 - Keep going, turn right, and you'll reach another fork in the road.  Take
the left path (with rings).  After going through some doors, you'll see GUN 
soldiers fighting number 18.  Take him out.

19 - Take the right path, going through several doors, and you'll reach Gun 
Lift room #4.  There will be two ACs hovering over a bomb on the opposite 
side of the room, but ignore them for now.  Instead, go left and through 
the door.  Go through some doors, roll under the wall, go through several 
more doors, and you'll find the other often-missed AC, number 19.  

20 - Go back to Gun Lift room #4 and take out number 20 on the opposite side.

21 - Right next to 20.  To make it easier, blow up the bomb near them from a 
distance.  Hit the Save Point here.

22 - Hop in the turret, and as you go out into space, you'll immediately face 
AC number 22.  

23 - Right next to 22.  

24 - Keep going a little farther, and number 24 will be on the right side of 
this turret ride, near a bright light.

25 - This is another often-missed one.  It's on the left side of the turret, 
half-hidden behind a thing that juts out of the side of the wall.  This may be 
the one Maria refers to as "hidden in the shadows."  

26 - Hit the Save Point in Gun Lift room #5.  Blast through the meteorites, 
and all is well until you get to the end of this ride, where an AC will pop 
out right in front of you as you go through the entry doors into Gun Lift 
room #6.  

27 - Go up the blue ramp and hit the Save Point that is located inside the 
room the GUN soldiers are shooting at.  Then, go through the other door in 
this Gun Lift room and hit the switch located behind the blue electric energy
field thing to open the door.  Go through and you'll reach a room with a HUGE 
AC.  Defeat him, and you got 27. 

28 - Either go down three lifts or jump into the Gun Lift room #7.  Hit the 
Save Point.  Ignore the two doors here unless you wanna pick up some grenade 
launcher ammo.  The other leads to the goal for the normal mission.  Just hop 
in the turret, go out in space, and you can blast number 28.  

29 - A little bit farther up ahead on the turret ride is number 29.    

30 - Just a little bit past number 29 is AC number 30, still on the turret 
ride.

31 - Also on the turret ride is AC number 31.  All of these are pretty much 
in a row.

32 - At the end of this turret ride, before the doors, is number 32.  He's 
right in your path, so take him out quickly.

33 - As you go into Gun Lift room #8, AC number 33 will be right above and 
to the right of you.  Take him out, and hit the Save Point in here.  Don't 
worry about the two doors in here, unless you want an extra life and some 
rings.  If so, use the grenade launcher (ammo is located in the left door's 
room) and blow up the wall in the right room.  You'll also find a key in 
there.

34 - Hop in the turret.  You'll notice the outside space is really big, and 
there are lots of platforms and interconnecting green paths up ahead.  
Don't worry about them.  You'll come across number 34 as he hovers above a 
platform up ahead.  

35 - Hop into the next turret right after defeating number 34, and just as 
you end the turret ride, number 35 will be there. 

I know by now we all most likely know where all the bombs in centeralcity are, but just in
case you don't i'll tell you where to find them.

#1: To get to the first giant bomb, when you first start the stage, go where
Doom's eye is. There should be two black and red crates (the one on the right
contain an alien gun if you need it). Right after, there is one alien that you
should just ignore if you are doing the dark mission, but behind him there is a
pack of dynamite. Use the gun you found in the crate to make it explode which
should reveal a bumper. Use that bumper to get to the top of the building. Use
the weight in front of you to get to checkpoint 1 and you should see the first
giant bomb right in front of you. To set if off, just fire at it. (make sure
you are not too close to it when it explode or you'll get hurt)

#2: To get to the second giant bomb, go past the giant bomb you just set off
and you should see a metal path that connects two building. Cross it and you
will meet Knuckles who will ask you to help him destroy the 20 small bombs.
Ignore Knuckles, jump on top of the weight and get on top of the other
building. Now you will need to use the triangle jump to get to the other side,
where the second bomb is. To make sure you reach it, start your triangle jump
on the left wall. The bomb will be right there with an alien, just ignore the
alien and shoot the bomb.

#3: This bomb will destroy a part of the wall right beside it. That will reveal
a few rings and a rocket. Do not take the rocket but jump on the road below.
You should see a blue light floating. Just touch it to awaken Hero Shadow. Use
Chaos Control right away to get to the 3rd checkpoint. From there do a 180 and
you should see checkpoint #3, turn left at the checkpoint and get on the step
on your right, just before the convertible, and up another step on your right
again, the 3rd bomb should be in a cage there. To open the cage you need to
destroy all of the Gun Troopers in front of it and a few of the one beside it.
Once the cage is open, just shoot the bomb again.

#4: Jump from the building you are on and head for the tunnel in front of you.
(if you don't see the tunnel, it is where the small bomb is, wait for it to
explode to open the tunnel for you, it should explode as soon as you are close
to it)  Get in the GUN vehicle, which is at the entrance of the tunnel on your
left. Once you are in the toxic substance, go straight all the way to the end
of that road and you should see bomb number 4 in a cage behind some GUN
Troopers again. Destroy all of the GUN Troopers to reveal bomb number 4 and
shoot it to activate it.

#5: Once the bomb is activate, you should see a dynamite pack behind it, shoot
it to get rid of the wall. Behind it there is a pole, use it to go up. You
should end up at checkpoint number 4. Run pass all of the Aliens and Troopers
in that street and take the rocket at the end of it (behind the giant Alien) it
will bring you to checkpoint number 5, from there use the GUN vehicle to cross
the toxic substance again. On the other side you should see a few GUN Troopers,
destroy the first one. Destroy the red car in the right corner to find a spring
to go up and you will find bomb #5 in a cage behind a GUN Trooper, destroy the
GUN Trooper to open the cage and set off the last bomb.

I also see people complaining because they can't find the bombs in Mad Matrix. So follow
this link and there is a guid to tell you where to go. there is also a map of The Doom,
and Lost impact incase you still get lost in there.

hedgehog

You may have noticed this, but everytime you compleat a story you get a special weapon.
here is where I'll talk about them.

Neutral         Egg Vacuum Level
Pure Evil Samurai Blade Level
Pure Good Heal Gun Level
Slightly Evil Satellite Laser Level
Slightly Good Omochao Gun Level

If you don't know what Neutral, Pure evil, slightly evil, etc... is I'll tell you. the
Neutral ending is the set of levels in the middle. slightly evil is the once above. pure
evil is the one above. slightly good is the one just below the nutral levels. Pure good is
below that. On thing you may be asking is. "How do i be
good/evil/neutral/whatever?" Well if you want to be pure evil keep doing what black
doom says. if you want to be slightly evil. do one level as bad, and the rest just do what
shadow says, and run through the level, and either get the chaos emerald, or get out! if
you want to be neutral just keep doing the shadow thing by running through getting the
emerald, and beating it without doing any real things. slightly good. Like what you have
to do for slightly evil. Just Do one good thing, and then do the shadow thing. Pure good.
Keep doing the good thing, and doing what the good guy says.
Now you might be wondering what they all do? Well I'll tell you. The Egg Vacume will suc.k
up all of your enamies, and boxes. (It wont take the really big enamies.) After you take
20 people it will expload, and you get more lives. Once upgraded to level 2 this doesn't
really do anything else.
Samari blade: This is just a normal sword. When you upgrade it to level 2 when you attack
it will shot something like a gun.
Heal Gun: This gun will heal gun soldeors and the black creators. I think it heals more
when level 2 but i'm not compleatly sure.
Satalite lasor: This gun shoots a little light you can target people with it. Whoever is
targeted when you let it shoot gets blasted by a big laser coming from above! Think of how
 freaking cool that must be?! BAM! This doesn't do anything else when upgraded to level
two.
Omochao gun: For those of you who don't like Omochao you might like this gun. It is
colored like him, and shoots omochao heads. It makes a popping noise when shooted. When
upgraded to level two the heads bonce when they hit walls.
Now you can't just beat the story just like you did before to get level two weapons. You
might notice that when you get to the last mission for a story you can only do two things.
the first time you can do the good, or bad one. But if you wanted to make a level 2
weapone you have to do the other. So if you were givin a choice between good or bad, and
you chose bad. The next time you have to be good. (This is required to get the last
story.)
