Team Fortress 2 has a new map called Gold Rush, which seems to be a takeoff on the Old West, and a new mode that goes by the name of Payload, which is what you play on that map. Steam users can get that update right now. Also, there are new medic weapons and achievements, which means it must be pretty sweet to be a medic in the Old West.
So, PC users, you can buck up. Something good comes to you this week, after all. Even if you are jealous watching all of your friends giggle in joyous rapture while playing GTA IV.
