[+] Hint: Easy Research Points

Hint: Easy Research Points

Wait for a Splicer to trip an alarm, causing two security bots to show up. Start rolling the Research Camera on one bot while it's killing the splicer and then shoot at it with one of the rapid fire weapons like the machine gun or the rivet gun. This should yield 600-800 research points per bot and there's no risk involved. Note: The fire ammo for the shotgun incurs massive bonuses for research, so zapping a Splicer and then hitting it with a few rounds repeatedly can yield up to 1100 research points depending on which Splicer and which research tonics one is using.

[+] Hint: Easy Security Research

Hint: Easy Security Research

To hack, or destroy it for research, that is the question... not anymore.

Find a hackable vending/health machine next to or near a Bot Shutdown Panel.

Hack the machine and intentionally hit a red spot to call in enemy bots, immediately turn and Snap the camera on one, then shut them down at the panel.

The now disabled bot is still highlighted by the research camera and you can splice and dice in researching ease.

A perfect location for this is at the end of Pauper's Drop just before getting back on the train. Forward and left from the train is an aid station next to a shutdown panel inside a small office with a window. You can hack the Health station and snap the camera through the window then disable the bots before they can even get a shot off.

Just don't hack the health on your way into the level and be careful with your aim because you may destroy the aid station.

[-] Hint: Telekinesis for Free

Hint: Telekinesis for Free

You can use Telekinesis to pull normal items toward you without using any of your Eve reserve. Your Eve is only used up when you release the trigger and throw an item using Telekinesis. This means you can use Telekinesis to pull items like ammo and first aid kits toward you to grab without wasting any meter. However, if you grab an item that you've already maxed out, you'll be stuck holding it with Telekinesis--or releasing the trigger to throw it and waste your meter.

However, if you pull up the plasmid wheel and select another plasmid attack, you can release the trigger to drop the item without Telekinesis automatically throwing it. This way you won't waste any meter dropping an item that you can't carry. This also works for pulling electrified trip wires out of walls. Pull the item toward you with Telekinesis and, without releasing the trigger, pull up the plasmid wheel to select another plasmid. When you close the plasmid wheel and release the trigger, you'll simply drop the item. No Eve meter spent.

[+] Hint: Rumbler Fumble

Hint: Rumbler Fumble

When you fight a Rumbler -- the Big Daddy with rockets -- use telekinesis to grab the rockets it fires and turn them back towards it for an easy victory.

[+] Hint: Buddy Bots

Hint: Buddy Bots

When security bots appear after an alarm is triggered, hack them and they will stick around and fight for you. You may want to stun them with an electric attack first.

[+] Hint: Hacking for Loot

Hint: Hacking for Loot
