I am making a Halo 4 forge map, and the goal of each team is to get three spartans into the other teams base at the same time, causing them to win. They don't all have to arrive at one time, I just want three Spartans in the base at any point. I can't find a way for this to work. I've tried using fusion coils, land mines and such, but I can't get it to function just right. Can anyone think of any game type, any mechanism that allows a team to win by getting three people in the others base? Any help is greatly appreciated.
