Before you fight the second Big Sister (if you are harvesting ADAM but saving the girls), you will get an Enrage Plasmid. There are two bodies to scrounge ADAM from. One is more easily securable, which has a security camera, a rocket launcher bot, and a large puddle of water in this area. The Big Daddy comes back multiple times. If you drop off the little girl in her hole near here, you can wait for the Big Sister to show up. Then, enrage the Big Daddy so that he will take on and kill the Big Sister. Your only concern will be Splicers and the Big Daddy after he is done with the Big Sister.

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

There are 2 Silver Trophies, and 1 Gold Trophy.

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.

Locate a hackable vending or health machine next to or near a Bot Shutdown Panel. Hack the machine and stop the pointer on the red to activate the Security Bots to come for you. Quickly turn and snap the camera on one then shut them down at the panel. The disabled bot is still highlighted by the research camera and you can research Security easily.

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.
