Infinite Objective Finder-One PressAdded 23 Feb 2010, ID #2462
With this Cheat, I will teach you how to obtain Infinite Objective finder with the Push of a button. First, find a spot where there are the Necromorphs that shoot missiles at you and look like little heads with tentacles. Use your Objective Finder (L3) until one of the Necromorphs forces you into close-combat where you have to press X a bigillion times. Now, you will have the Objective Finder on FULL TIME!! And you don't even have to press the button. This will go away once you press L3, so don't do it.
Get The "Theres Always Peng" TrophyAdded 10 Jul 2009, ID #1879
First, you can only get this trophy near the end of the game. In the chapter where you return to where the game originally started, look off the side of the bridge. Keep looking until you see a shiny object. Now, use your Kenisis or whatever (the ability that lets you pick up syuff) and point at the object. You will now have the Peng trophy once you pick it up. -1122andyozz33
