A trailer has been released of the anticipated upcoming modification for Half-Life, Natural Selection.
Multiplayer-only Half-life mod where one team plays marines and the other plays aliens. The humans must keep their cool and work together to assault an alien-infested spacecraft or colony. Marines vs. marines and aliens vs. aliens scenarios are also supported.
Grab the trailer now
from AusGamers. Apparently the mod has "gone gold", so stay tuned for the release. We'll try and get a server up so people can have a bash.
Update: Clint let us know in the comments that there is an official release date set of October 31 - Halloween!
