Zanzibar Warthog trick

To do this trick, go to the Zanzibar (Level) and choose Dreadnaut. Drive both Warthogs and both Ghosts to the big wheel in the middle. Drive 1 hog into the wheel, get out, jump into the other one, and push the 1st Hog so the passenger seat is in line with the spokes of the wheel. If done correctly, the Warthog will fall on top of the inner wheel, making a great sniping spot. Also can be done with Ghosts.
