This is a neat little way to make tanks go flying. First, set Scorpions as Primary Heavy Vehicle on Coagulation (Level) . Then drive up the rock near the shotgun spawn until the tank flips over. Then, have the other person drive up the flipped tank with another Scorpion so that one is completely on top of the other. Then flip over the bottom tank and the top tank will go flying across the map, continuously spinning. Tanks can be kept in the air for a surprising amount of time, bouncing off walls, the ground, the invisible ceiling, and sometimes clipping onto the top of the map. Of course, if this last occurs, the tank's driver will be instantly killed by the Guardians.
Tank jumping can also occur, with a bit more work, in campaign. In the level Delta Halo, get the Scorpion to the chapter "You Break It, You Buy It." After killing all the enemies in the area, blow up the energy shield right next to the fountain and center the tank on the shield emitter. Sit there until the shield turns on. Move or fire your cannon, and you should go flying around, spinning the whole time. This is often far more entertaining, although also more lethal, then the multiplayer version. This can also be accomplished slightly later on in the level, when you come up on the final outdoor structure. If the trick works, the Scorpion will be flung into the air, often exploding.
