The official website for a upcoming game - Natural Selection 2  has been updated with its official logo and also a teaser trailer, w00t! Calling out to all NS players before, it is time to awaken again and embrace the war between the Space Marines and the Kharaa (if they still call it in NS2). Trailer video shows a promising release date around Fall 2009. (well, unless it delays)

HQ version

Definitely looks promising and pre-order is now available on Steam. To know more info about this game, check out their official website here

PS: that big ass monster is known as a Onos in Ns1.
