If you’re anything like me, you saw someone rocking a rad alien hat inTeam Fortress 2, wondered how they acquired such a thing, then proceeded to make a sandwich and forget all about it.
Thanks to PC Gamer, I have been reminded. By earning the “Hat Trick” achievement inAlien Swarm— beat two co-op missions online — the sweet Parasite hat can be yours inTF2. ConsideringAlien Swarmis a free download, this is totally worth doing.

I’m probably the millionth person to say this, but seriously, aHalf-LifeHeadcrab would make for a cool hat.
