Alien Swarm

Alien Swarm – releases today on Steam for free

Alien Swarm looks quite similar to a game that also has a very similar sounding name; Alien Breed. The latter is, of course, a remake of an old Amiga game, so has the classic value. But to be quite honest, Alien Swarm really shows how the top-down xenomorph shoot-em-up genre should be done. Not to mention the fact that Alien Swarm is absolutely free.
