- Did you look for the Halo 3Overload Glitch?
The Overload Glitch is a Halo 2 Glitch that can be only done via Xbox Live or system link.
First, go to an object that is not part of the environment, but part of the scenery (bridge on Zanzibar, floating platform on Midship etc.). Then get seven or more people to stand on it and put as many vehicles on the object as well. Have the people then look down. The object will eventually overload and disappear.
