Allright, the first part is easy, spend 2 hours destroying all the generators (tube things sticking out of the ground)
(BTW the necro ball can go through floors & walls, so if you're stuck, look around)
2nd part, (blue doors) chain grab to the room above the entrances (unclear but can't help ya) and take out the spiky ball things, and the third part,
gay as hell, just kill around 5 cycles of enemies in the control room, then the exit mark appears. -Jack out

*growls* why is Europe the last to get the great games? I ain't seen it around yet

That was alot of help considering that the only guide out is official and u have to payfor it, you cant find a walkthrough anywhere/. Me and my friend went through the game like hot knife through butter but got stuck up in space station Thx alot for the help man! Greatly appreciated!

Thanks alot! Could you tell us where all the generators are thats where I get lost. Thanks!

do the markers for 'chain grab' appear when you knock out all the generators? I think that I have knocked them all out - but I can't find any place near the blue doors to chain grab onto. Am I missing something?
