BattleTanx: Global Assault Cheats

When you have 15 or more of a certain weapon(works well with All Weapons cheat) you can press A+B at the same time to fire an enhanced version of the weapon.

I dont know why anyone would want to do this, but this is useful in multiplayer when you need a different tank. To do this, press all 4 C-buttons at the same time to commit suicide!
