Flying master chief!!!!!(or elite)
First of all you need to go on the coagulation map on multiplayer and select the vehicles as either the warthog or the spectre also get the energy sword.
Now get the energy sword and park the spectre or warthog at the red base where the hill begins to get in the way now player 1 must get in the passenger seat of the warthog or spectre with the energy sword as your weapon and player 2 must stand so that player 1's target goes red, now player 1 must hold the R button until player 2 runs to the other end of the map then when player 2 is stood up against the wall at the other side of the map now player 1 must press Y to get out of the warthog or spectre.
If done correctly your character should fly all the way accross the map until it reaches the other side of the map and land on a large ridge sticking out of the cliff face. Happy flying!!!!!!!!! Timmy123
