Go through and pick up the Art of War 2 on the platform, jump up to the ledge and shimmy right to get the X-Force Wolverine Action Figure, and then go back.
Keep the teleporter in the middle of the room. Move around the catwalk to the control room. You'll come to the next checkpoint in a larger room.
