In halo 2 i played a custom game where there were infinite number of rounds, it was 1v1 until 1 person died, once a person died another person (who was watching the two people) spawns and then so on, once a person got to 15 kills or w/e you wanted to make it up to the game ended. Is there a way to make this custom game in halo 3. i couldn't figure out how to do it.
