This a RTS style of the James Cameron´s film Avatar. You can choose one of two possible factions; the RDA (aka humans), and the Na'vi, the blue aliens. This Mod its probably a C&C Style building for the RDA, and a normal building for the Na'vi. The two factions contains superweapons, upgradeable troops and abilities, and much more.
