This is for when you are low on health, when you see one of the bugs flying around press X near it to eat it and it will restore low health meters.

To easily take out the riot guards, simply give the BLACK panel on their backs a couple of shot-gun blasts.

There are two parts to the snitch list. One is hidden in the work pass room where there are the two guards and the mechanic. Search for a loose panel behind the crates. After you give the package to Jagger Valance and you get the mission to get the bomb, head back to the second floor (like you're heading back to the upper mines). On you're way back you're going to see 2 miners standing around. Take them out. One of them has the snitch list plus a little axe-like club I think you'll really like.

In the "showers" chapter, right after Riddick gets his eyeshine, stealth kill the guards near the lockers without letting them activate the alarm. Once that's over with, open the lockers and you'll find some UD, assault rifles, a pack of smokes, and a guard suit. Put on the suit and you can walk around without having to kill anyone (but you can't go into stealth mode, or kill any lights, otherwise they'll figure out you're a prisoner). You can talk to the guards, giving you some valuable information when you reach the "Guards' Quarters" chapter and try to find Abbot. At the place where Riddick uses the retina scanner, go to the end of the room and to your left (the side where you first come through) will be a ventilation shaft. Enter and you'll find yourself in a small room with assault rifles and a light armor guard suit. Use the armor, and you can still act as a guard. This secret allows you to obtain some extra UD, and makes everything much easier when you try to reach Abbot.
