Alien Swarm just got a big upgrade. It has been re-released as Alien Swarm: Reactive Drop with more campaigns, more multiplayer options (including co-op bots to help fill out your party), Steam Workshop support for community-made campaigns and mods, and more.
And it's still completely free!
I had a lot of fun playing Alien Swarm with other DC members, but it always seemed unfairly hard if you couldn't get a full party of 4 players. But now with the addition of bots, it's very doable to complete the original campaign with even just two competent players.
I haven't tried any of the new campaigns yet, but I'm looking forward to doing so. Hopefully with folks from DC again.
