Already included in the special edition of Aliens vs. Predator, the Swarm map pack has been slated for a March 18th release for the general public priced at $7, which will consist of two competitive multiplayer maps and two cooperative mode maps.
“Docks” and “Machine” are available for the six competitive modes (Deathmatch, Predator Hunt, Infestation, Species Deathmatch, Mixed Species Deathmatch and Domination).
While “Outpost” and “Hive” are available for the cooperative mode, which requires space marines to work together for their survival against Aliens set in an abandoned colony and an Alien breeding ground.
