my friends and i just got done doing the 2nd power node (lil haxx0r should have a post like this, me and him are friends and we were in the same game finding this stuff out) we got to the room before the p.a.p. and found a clock with a knife in it. its the 3rd power node you have to make the knife do a 360* its easy, the room before the p.a.p. is where you need to be (right next to the clock) look at the floor and its just like the clock (if you have good eyes) walk on the steelish part one big O. the clock well make a sound (all node make a creepy sound so you know where they are and if you are close) when you complete it, it should set off a nuke (like the powerup) thats the 3rd node! my friend lil haxxor is working on the last node!!!!!!!!!
