A new Steam Weekend Deal is up and the sale is for 75% off all Serious Sam HD games. Four packs are also available.

These are seriously really fun to play online co-op. You can load up a server with like 12 people all playing through the entire game. The bosses are huge and you get crazy guns firing all over the place. So much fun. You’ll die like a million times too but no one cares lol.
