BioShock Hints

There are three different endings in the game, depending on how the Little Sisters were treated. If more than one Little Sister was harvested, the "bad" ending will play. If no Little Sisters were harvested, the "good" ending will play. If one Little Sister was harvested, but the rest were rescued, a third ending will play.

After hacking a robot, it will begin firing at your enemies. If the robot gets hit, it will begin to lose health, catch on fire, and eventually blow up. To stop this from happening, deactivate the robot (press A while pointing at the robot), then reactivate it a few seconds later. This should make the robot have full health again.

Use the Incinerate Plasmid on any slot machine to corrupt the machine. You will usually always win money when you use the burnt out machine.

While normally the various alcoholic beverages (for example, Arcadia Merlot, Old Tom Whiskey, etc.) scattered throughout the game are used to recover health, they can be turned into Molotov cocktails similar to those used by the "Nitro Splicer" enemy. To do this, use a source of flame, such as the chemical thrower, the Incinerate! Plasmid, or an environmental source. Ignite the alcohol bottle, pick it up with the Telekinesis Plasmid, and throw it at the enemy of choice.

1: In Peach Wilkins' hideout (Neptune's Bounty), bottom floor. As soon as you come downstairs, it is directly in front of you.

2: On the way to Farmer's Market in Arcadia, the station is located to the left after you go up the first stairs coming from Tree Farm.

3: Go to Winery's basement in Farmer's Market. There is a flooded area with one of them attached to the wall. It is in front of you when you come down the stairs; just keep going forward.

4: In Fort Frolic, from the Atrium bottom floor, go towards the bathrooms. Then, move right and follow the path until you see some small stairs to your right leading up to a door. Go inside, then go down into the basement. The basement is filled with cigars and other stuff. The upgrade station is on the wall.

5: Go to Poseidon Plaza in Fort Frolic. Go to the other end of the bottom floor (the opposite end of where you enter). Go into Sinclair Spirits (the room that has a corpse on a sort of "altar"). In the basement of this store is the station.

6: In Hephaestus Core Room, go down to the bottom floor, and run around (literary). Eventually you will see it attached to the wall.

7: In Hephaestus, Kyburz's office. It is attached to the left wall (back turned to the entrance) in the rear of the room.

8: At the bottom floor of the Mercury Suites area, on the back of the center pillar.

9: In Sander Cohen's secret room, in the Olympus Heights' Mercury Suites area.

10: Go to Atlas' Headquarters in Apollo Square (Fontaine's Home For The Poor area). It is located on the fourth floor. Go down the stairs in the room and look to the right. The station will be in front of you.

11: When you enter Point Prometheus and chase Fontaine, eventually you will end up in a little square, and Fontaine will go behind a locked Museum door. At the opposite end of this square (from where you came) is a dead Big Daddy. Next to it is the upgrade.

12: In the Voice changing labs in Point Prometheus, one of the labs has it.

The key to Chompers' Dental in the Medical Pavilion is acquired by using Telekinesis through the broken window to the left of the door. There should be a corpse hanging over the broken window. The key should be grabbed with Telekinesis because it is hanging on a wall on the other side of the window. You can get Telekinesis in an area near here. You will need to get that first, but do not follow the arrow back to the rubble that you need to get rid of until you explore Chompers' Dental. There is a safe and other good items inside. Note: Both Telekinesis and Chompers' Dental are near where you find the shotgun.

When fighting a Big Daddy, use armor piercing rounds from the machine gun or pistol. For a more effective way of killing, launch frag grenades and run out a door. The Big Daddy will follow you. Fire proximity mines at the door, and when it walks through it will be damaged or destroyed.

Once you have obtained the crossbow and at least five Trap Bolts, it is easy to kill a Big Daddy. Face a wall and stand about three feet away. Make sure it is not something that the bolts can bounce off of, and you have at least a ten foot long straight wall. Once you are better skilled at this technique, you can try for shorter lengths if desired. Point straight ahead and fire a bolt. Take about two steps to the left or right, depending on your location and which way the Bid Daddy is facing, and fire another. Once you fire all five bolts, shoot the Big Daddy once with anything. If done correctly, it will run through the line of traps, taking enough of his health away so he can be killed with just a few more shots. Note: This may not work in an open area because Big Daddies strafe frequently. If you have the damage increase for the crossbow, it will only take three or four bolts to kill him. Do not crouch while setting up the traps. If the Big Daddy walks another way and gets out of sight, you may need to go back to get him. If you do get him, you can crouch under the set traps. An easy way to trigger bolt traps is to pick up something with Telekinesis and drag the object through it.

Once you get the Security Bullseye Plasmid, set off an alarm either by hacking or being spotted by a security camera. Then, throw the Security Bullseye at the Big Daddy. You may have to do this more than once depending on how much health the Big Daddy has when starting out. Try to avoid the battle because the crossfire and exploding bots will damage your health. The only problem with this technique is that once the Big Daddy is taken down, the bots will come after you. Be prepared to either run and hide, fight them off, or pay to shut them down.

To defeat Frank Fontaine very fast, when you first enter the room, hit him with the tool the Little Sisters gave you. Fight him when he throws you off. Once he is back on the bed, run up and hit him again with the tool to drain his Adam. This works a lot faster due to him only having four or five jars of Adam to drain, and the fights are not very long afterwards.

Once the dark cloud envelopes the icy battlefield upon which you must face Peach Wilkins, save the game, and locate the hostile turret at the end of the room when the cloud clears. Load the game, and run to it before the cloud clears, so that you can quickly freeze or shock it. Then, hack it so it shoots your enemies. Crouch down by the area to your right when facing the turret. There are a few barriers here to protect you from enemy fire. However, to avoid damage by Wilkins' grenades, keep Telekinesis as your active Plasmid. He will avoid the turret's fire, but as long as you stay behind the barriers by the turret he will stay at a safe distance. This gives you time to calmly return his grenades using Telekinesis until he dies. The turret will take out most of the Splicers. This method makes things much easier because it eliminates the hectic "run around and hit enemies with the wrench" strategy that is otherwise your only option. If the turret is not used as an ally, it can easily become a problem, along with the bots triggered by the security camera. By hiding near the allied turret however, you also hide from the camera's view.

If you are up against a stationary security robot (RPG, etc.), use Telekenesis to grab a crate or pallet. Hold it in front of you until you can find a place to hide and know what to do next. The item you hold up will block some attacks.

Do not harvest a single Little Sister throughout the game. Tenebaum will reward you with gifts (including Adam) every time you rescue three Little Sisters. This proves more effective, as you get the same amount of Adam as you would if you harvested them, but you also get the achievement.

When buying Plasmids, Tonics, and Upgrades from the Gatherer's Garden, always buy the Tonics first. Then, make sure you search every area for other Tonics. When you reach Point Prometheus, there will be three Tonics to find. The rest of the Tonics are available in the Gatherer's Garden. This will ensure you get the achievement. Note: To check how many Tonics you have, go to a Gene Bank, and count each "track".

Atlas Fontaine, the the final Boss, has three different styles of attacks: Flame Plasmid, Ice Plasmid, and Electric Plasmid Form. An easy way to defeat him in the first part is to use your Ice Plasmid and freeze him. Then, switch to your Telekinesis Plasmid. Grab an explosive tank, and throw it at him. Also, if desired, just use your telekinesis. He is very predictable if you are far away from him. Wait for him to throw a fire ball at you, then move out of the way. He will continue to run past you. Use this chance to fire the machine gun, which does the most damage to him. Once he goes back to his chamber to gain his life back, change to the Flame Plasmid, and get ready for some bots. Once he starts his routine of fire and run, shoot him with the Flame Plasmid as many times as possible. Continue to use the machine gun while he is aflame. He will now go back to his chamber one last time. He will now have electrical powers. Keep your Flame Plasmid ready. Shoot him with the Flame Plasmid, and he will run for the water. Once he jumps in the water and comes back out, hit him with it again. Be aware that there are Splicers all over as well; set them ablaze to get some extra life. There are many different ways to defeat him, but this is an easier way.

An easy way to defeat Atlas Fontaine is to make sure that you have the fully upgraded shotgun and the Decoy ability. After you drain his Adam, drop a decoy and while Atlas is attacking it, use the shot gun. After you have used all four rounds immediately cast Decoy again, reload your shotgun, then begin shooting him again. Repeat this until you have to drain his Adam. Once again, reload your shotgun and Plasmids before you drain his Adam. Then, start over using Decoy and the shotgun. Use health packs as needed and ignore any Splicers in the area, as they will be paying attention to your Decoy just like Atlas.

Okay.... there are parts in the game where u see many trap wires(electric wires) and u have to waste ammo to destroy them or u just get damage. I firgured out that when using telekenis on a dead body and moving it on a wire, the wires breaks and u can keep holding the body until u destroyed all the wires. Hope this helps!!!!!

Use 2-3 of the crossbow trap ammo on a big daddy, first line up 3 traps spaced apart in a line going across a room and then shoot the big daddy from a distance so he runs towards you. Stand where he will come for you, but go through the traps instead he will die after he hits them.

You know how sometimes in the acheivment part of the Xbox 360 it says secret acheivment, well ive discovered one firstly in Fort Frolic when you complete the master peice, wait for Sander Cohen to open that locked place with an ability, the kill him and unlock the music box.

Thats just a hint but to get the acheivment, just take a picture of him. The acheivment is called Irony

The rose splicers that teleport you can hit them with the incenerate and that is probably the easiest and funniest way to kill them...... please tell me if im wrong but im not.
