If people remember the mod that came out a while ago called Alien Swarm, the people who made it were hired by Valve and it's now available on Steam for free.

A free NASA game has been added to steam:

I started downloading it this morning, but had to go to work.

Looks like (as per usual) there's been an update to TF2 and Steam, so if ya're coming to LS you might want to update beforehand.

The only stuff on today's one I might be interested in is Killing Floor or Bioshock 2. Is Killing Floor worth picking up?
