[dabiggk]

Hi guys can anyone help me its driving me nuts this is! Bought a copy of dead space 2 the other day, I know where have I been its been out ages?? brilliant game btw. however I'm now stuck on chapter 10 of dead space 2 the centrifuge puzzle bit, where you have to find the 4 pipe pieces and put them in the tower in the center of the room so that the energy may flow etc, my problem is I can only find 3 pieces and there must be 4 because on the walk-throughs on youtube there are 4 and the tower has 4 slots. the missing piece I cant find is the one that should be above the bulk head sort of center height of the room slightly to the left just as you walk in but on my game it isn't there spent a long time looking for it and its no where to be seem, is this a known glitch or what? how do I sort this? am I just not seeing it? followed guides still cant find it, help from anyone is much appreciated thanks guys

There are 4. It should be somewhere in the room floating around. Maybe one got bumped into a glitchy area. There was a save spot just outside the centrifuge room that you probably (should have) used. Try reloading and look again. The spot that frustrated me was after starting the centrifuge. Bloody annoying, a search only gave more confusing answers, and there's no objective direction marker. It's actually so stupid. Just leave the centrifuge where you entered. There's the save spot. Keep going through the second door and voila, mini cutscene and you're on your way again.
