Natural Selection 2 is an immersive, multiplayer shooter that pits aliens against humans in a strategic and action-packed struggle for survival. It seamlessly combines a shooter/FPS gameplay with a strategy (RTS) game.

Whether you play as one of the elite marine Frontiersmen or the vicious alien Kharaa, you must use unique strategies and your abilities to win. Marines form persistent squads to find and destroy alien hives. Aliens can choose a wall-running Skulk, pudgy Gorge, flying Lerk, murderous Fade or gigantic Onos that can smash through doors.
