Melee a health station, and a health kit will come out.Easy money
Find an area that contains a working slot machine. For example, in 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. It is possible to max out your wallet in approximately ten minutes. Repeat this as many times as desired.Easy Security research
Find 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 alarm, thus triggering the Security Bots to come after you. Once you see them, quickly take a picture of one of them with the camera, then use the Bot Shutdown Panel to shut them down. The disabled bot will still be highlighted by the research camera, allowing you to research Security easily.Easy XP in Multiplayer mode
Have a friend join your game while it is in progress on any team-based game, putting him or her on the other team. Find a turret anywhere in the map, and make sure there is nobody around. You and your friend can hack the turret back and forth for 10 XP per hack. Repeat this as many times as desired. -From: Christian ManziEasy final battle
Fully research the Houdini Splicer. Have Natural Camouflage equipped. Immediately before the final battle, remain idle, and you will become invisible. No one will attack as long as you do not move. If you move, you will become visible again, and all enemies will attack; you cannot turn invisible while being hit. Once Eleanor says she can fight, summon her. She will distract and fight everyone, allowing you to stay invisible. She will eventually kill everyone so that you can escape.

Use the following trick to pull normal items toward you with Telekinesis and not use any Eve. Eve is only used when you release the button to 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 Eve. If you take an item you are already maxed out of, you will either be stuck holding it with Telekinesis or have to release the button to throw it and use some Eve. However, if you display the Plasmid wheel and select another Plasmid attack, you can release the button to drop the item without Telekinesis automatically throwing it. Thus, you will not use any Eve by dropping an item you cannot carry. This can also be used 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.Defeating Rumblers
