I call the game Rally Point Rally. Get a party of 4 to play this in matchmaking. Load up 8 double xp codes (a more and you'll lose them to xp credit capping.
The rules are simple. Everyone gets their own warthog and no one ventures to the opposite side il every one has an AI gunner (this process may take a minute due to the fact you have to shoo 2 AIs off of turrets on the base)
Then its a race to see who can get the most kills with their gunners... and anything in the hog goes. Ex you see some one roll thier hog... could splatter said AI whos is on the ground leaving them s.o.l.
when the game is over the winner gets a victory lap driving their warthog into the ring telepoter with the loaded onto his or hers warthog. Last one to the winners hog gets hood surf it with a turret.
