Last year, Valve released - for free - a game called Alien Swarm, which ended up with a visual style somewhere between the original Alien and a 1980s action figure. This early concept, though, shows something a little more unique.
I've been playing a little Alien Swarm this week. It's a pretty good game as is, but that's not why it was provided free of charge. No, it was provided free of charge so you kids could mess with it.
The Alien Swarm Unreal Tournament 2004 mod becomes a full, Source-powered four-player co-op tactics game, available for free on Steam this Monday, courtesy of the nice folks at Valve.
