Hide in a wall in multiplayer
I can't remember the exact name of the multi level but it's the circular one. It's not assault cradle or ancient vestiage. This cheat works best as the host of the game so you will be the colour orange. Turn into a ball and go around the outer part of the level (in ring shape) look on your radar when going around you should see a little passage way (there is one on each side of the entire level) that you can only go through as a ball. In there is some ammo for the electric lob gun go out to the other side slowly. Turn full size (as human shape) and don't hit the boost, depending what side you are on go to the left or right. On each side there is a wall that covers about half of you. look straight ahead and run backwards this will help more of the wall cover you. If you don't look straight ahead you will start to go left and right and not back. From there shoot enemies that try to come through the tunnel or in the arena.
