In the room after fighting the strange creature that mimics your every move, there are three horizontal crushers on both sides. Go to the side where the floor that has not collapsed. Pull the lever on that side (just to get the checkpoint), then take out a gun with and wait for the crushers to go back in. Now run and jump into the path of the crusher when it comes back out with the weapon still out. If timed correctly the impact will throw you into the ceiling with surprising results.
