Human Frontiersmen marines battle squicky aliens the Kharaa in a blend of first-person shooter and real-time strategy across dynamic levels both sides alter in their own way.

Natural Selection 2 is released on PC this fall. Pre-ordering for $20 gets you into the beta, or the $40 special edition also grants alpha access and exclusive black armour.
