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.

To blow up your tank press and hold all four C-buttons. This can be helpful if you want a different tank in Deathmatch.

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.

First start a game on any mode or level. Next pick up a Gun Buddy. Now back into a indistructable wall and try to lay it. If it dosen't work back up more and try again. Once you've layed it turn around and all you can see of it is the two barrels on the front of the gun. Now when a opponent comes by it will shoot it even though it is behind the wall and the enimie can't shoot through the wall so the enimie can't destroy it.

When you have more than fifteen guided missiles, select it and press and hold A+B at the same time. If done correctly the missile will be bigger and slower than the normal ones. Then while guiding the advanced missile press Z to fire lasers from the tip. (You only have a limited amount of lasers that can be fired. This does not use the lasers that your tank has.)

In a 2P game with two computers enabled, kill one player quickly. The loser's portion of the screen should be static, but under the control of the analog stick!
