the only way to do this cheat is with more then to people and a wraith. first you go to the part where you usually get a wharthog and face yourself toward the person i the wraith. stand there and he or she will boost you up and u will go very high stay straight and then move to the left. go to the rocks and go down to the bottom but dont go off the ledge. next the other person comes and sword cancels you thats x and the right trigger together then you let him do it to. finally u go to the top rock 1 2 3 and then the big one jump straight ahead and run almost go off the cliff but jump up the straight rock slant and turn then just have fan but u either die, suicide, end game or go to a crack and go down. have a great time on top of burrial mounds ps you suck at this game. written by a halo 2 favorable player code name B23 SILENT BLADE.
