#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.
