Back In The DayG 5

Not too tough at all as long as you have 4 controllers (or some rock band/guitar hero guitars)

Halo CE multiplayer, Blood Gulch map, CTF, and change the rules so it’s considered a “custom” game. All I did was increase the player movement speed and reduced the win condition to a single point. Then just use your primary controller to fetch the other teams flag and bring it back to base.
