Float to top of level:
To have your transformer float to the top of the level boundary, you will need the ability to climb walls. Go to any level with any vehicle form. Go to the boundary of any level that is formed by a wall that you can climb. Once you find one, climb to the top. Once you reach the top, you will fall. The instant that happens, keep tapping X while holding Up so that you stay at the top of the wall, but keep loosening your climbing grip. Eventually your Transformer will look like it is going to get on or over the wall. Once this happens, do not move the D-pad. Your Decepticon will slowly float to the top of the level boundary. From here you can move your view and look around, but moving your character will cause you to fall to the ground.
