it was me and my friends first time playing, and we were playing the level Halo. we just got the Warthog and we were driving towords that cave, except we thought we thought you went up the ledge on the left. My friend somehow had the back of the warthog hanging off the cliff and was trying to get the hog up it. After about thirty second, of trying to get get back up, he jumps put of the hog and i fall to me death.
