Note: Any active codes are disabled when a new area loads or intermission sequence plays. General codes are as follows:

When facing a Rumbler (Big Daddy with rockets) use Telekinesis to grab the rockets it fires then turn them back towards it.

Go to a health station and melee it. A health kit will come out.

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.
