Airlock is a semi-symmetrical map designed as a UNSC spaceship, featuring a special Anti-Gravity Room similar to that of Zealot or Anchor 9. The map is fairly small, and yet works with just about any number of players. however, it requires a custom gametype to work called: Orbital Elimination. I would definitely suggest checking this one out. Map Creator: xEpiiC Assasinx YouTube - Amazing Halo Reach Forges: Airlock
