When you are ready for another round of room rotation puzzle action, pull the switch. Move to the right and wait for the crate to drop. When it does, wait for the room to rotate a little more and push it to the right until it is onthe edge of the platform. Use the crate to jump across the gap before the small gate comes down or you will be crushed by the boulder we jumped over earlier.
Once you are safely on rotation-free ground, continue to the right, jump onto the cog and ride it to the right. Jump off and continue until you see a lone figure sitting on the ground. As you approach it, a brain slug will ambush you and force you to run back the way you came.
Jump back across the cog and up to the higher platform; continue until you reach the beam of light. Run back to the right, over the cog. You will notice that the room has now transformed into something quite different. Jump across the gap onto the conveyor belt, run up to the first crusher and when it is safe to do so, jump inside and out the other side onto a second conveyor.
Approach the second crusher and grab onto the left-hand side of the lowersection. Ride it to the top of the room, and when it starts to separate runacross and jump down to the next conveyor below. You will see the demonic growth on the ceiling. So time a jump to land on one of the boxes and then up again to the growth to remove the brain slug.
Achievement/Trophy: Stand on the left hand side of the third conveyor here and wait for the crusher to descend, use one of the crates to jump up and grab onto the right hand ledge of the crusher. Ride it to the top and when it is safe to do so, jump down to the left. When the crusher comes down again, hang onto the left side of it and at the top, jump across to the hanging ladder nearby. Climb to the top and follow the passage way to the right to find an egg, squish it for the achievement/trophy - Backtracking.
At the end of the third conveyor is a cog, jump aboard and ride it to the top, from here jump to the ladder and climb up.
