Secret - Doom Buggy
by Unregistered Oct 26, 2009
When you unlock the level hotter than hell go over the fence find the black track and follow it. If you keep following it and don't go of it you will find the doom buggy. when you are in it there is a big ramp made of metal sheets, it's next to a plane get a really big run up and then jump it if you have a big enough run up you will jump the hole stadium.
