From all accounts, sales of the new Aliens Vs Predator game from developer Rebellion and publisher Sega have been quite solid. Now the first person shooter based on the movie monsters is getting its first downloadable map pack on March 18, according to Sega's European web site.

The four maps in the Swarm map pack were included in the special edition versions of the game. The PC port didn't get a special edition so these maps are entirely new for our platform. Two of the maps, Docks and Machine, are for the Deathmatch, Predator Hunt, Infestation, Species Deathmatch, Mixed Species Deathmatch and Domination gameplay modes. The other two maps, Outpost and Hive, are specifically for the game's four player co-op Survivor mode. The map pack isn't free; it should be priced around $6 when it's released.
