I lament, often on an almost daily basis about the lack of co-op support in our modern gaming society. So lo and behold what do the Valve Gods gift us with? An up to 4-player co-op game for free! Alien Swarm was originally an Unreal Tournament mod released in 2004. This release was actually developed by the original team after they had been scooped up by Valve (according to Wikipedia). It’s a top down 3rd person shooter with a sci-fi flavor. There’s not a whole lot in terms of plot, but that is not important. The only facts that need be known are that there are waves of aliens to kill on a space ship with your real life buddies.
