Float in air glitch
This glitch is a way to stay in the air forever. Choose multiplayer and choose any level where you can fall very far down, such as the treehouse level. Choose the start with all weapons cheat and play normally. Chose the gun that turns into that remote-control spider thing and jump off the treehouse. Don't stop pressing the jump button (A default) and you can move it around in the air and explore.
