BioShock 2

Hack a vending machine and stop the needle in the blue section to get free ammo or a free Eve. When the same thing is done at a health station you can get a first-aid kit.

Use the following trick to use Telekinesis to pull normal items toward you without using any of your Eve reserve. Eve is only used when you release the trigger and throw an item with Telekinesis. Use Telekinesis to pull items such as ammunition or first aid kits toward you to collect without wasting any of your meter. Note that if you take an item that you are already maxed out of, you will be stuck holding it with Telekinesis or release the trigger to throw it and waste your meter. However, if you display the Plasmid wheel and select another Plasmid attack, you can release the trigger to drop the item without Telekinesis automatically throwing it. By doing this you will not waste any of your meter dropping an item that you cannot carry. This also can be done when pulling electrified trip wires out of walls. To do this, pull the item toward you with Telekinesis and without releasing the trigger, display the Plasmid wheel to select another plasmid. When you close the Plasmid wheel and release the trigger you will drop the item.

• Hack Security Bots when they appear after an alarm is triggered. They will remain in the area and fight for you. Note: Try stunning them with an electric attack first.

• There is an easy way to collect Security Bots to fight with you. First, locate a Bot Shutdown Panel that is quickly accessible near a vending machine. Hack the vending machine, but stop the pointer on the red to activate the Security Bots to come for you. Quickly run to the Bot Shutdown Panel and throw the switch. Then, locate a deactivated Security Bot and hack it. That Bot is now aiding you. Note: You can only have two Security Bots aiding you at one time.

Reach the given rank to unlock each bonus or item.

Complete the following achievements to unlock Xbox Live Gamerscore points.

Play the Siren Alley level inside the Mermaids Lounge. Go upstairs into the room on the right side of the balcony that contains the slot machines. As you enter the room, turn left and play the right-hand machine of the two that are facing you. Save the game before you start and resave it every time your total money increases above where you started. If the machine does not payout after about a dozen turns, reload your saved game. By doing this you can maximize your wallet in about ten to fifteen minutes. It will now be easy to fully load up on ammunition and health/EVE boosts for fighting the Big Daddies. Repeat this for each additional Little Sister on the level.
