As promised earlier this month, the Steam service now has the first downloadable content expansion for the recently first person shooter Aliens Vs Predator. The Swarm map pack for the Rebellion developed game can be purchased and downloaded via Steam for $7.99

The four maps in the Swarm map pack were included in the special edition console versions of the game but the PC port didn't get a special edition so these maps are entirely new for our platform. Two of the maps, Docks and Outpost, are for the Deathmatch, Predator Hunt, Infestation, Species Deathmatch, Mixed Species Deathmatch and Domination gameplay modes. The other two maps, Machine and Hive, are specifically for the game's four player co-op Survivor mode.
