In the multiplayer Area 51 level there is a UFO. If you shoot the UFO you get this cool gyrating light show. In between the upper left and upper right corners is another UFO. If you blow both of them up and drive into the light show you can warp between the two points.

Better Weapons
To get better weapons in multi-player collect 15 or more of a weapon and press A+B at the same time. You will fire a modified blast of the weapon you fire. This code doesn't work with grenades.
