Glitches
In the Blood Gulch level with two tanks, there is a very entertaining glitch. You flip over one tank by driving it up the wall then jump out of it. It might take a few tries. One this is done, you take the other tank, and drive up over the flipped tank. You should now have one tank on top of the other. Now that this is done, either you, or a friend flips over the lower tank. The tank on top is launched all the way to the other end of the map.
