I think would it be cool if it came a gamemode where there are 3(Red,Blue and Yellow) teams, 2(Blue and Yellow) teams defending a mammoth(just a example) and 1(Red) trying to destroy it, if the 2 teams lose the mammoth will blow up(or something) and the other team will win and then its 2(Red and Blue) teams again and then the other 1(Yellow) team will try to destroy it, it will be a total of 3-6-9 rounds depending on how many players a lobby with a total of 30, and the gamemode can be called like Escort or something but I don't know but its tottaly up to 343 to put this gamemode in to the game or not....
