This week was essentially Left 4 Dead week for me, since I finally got my hands on the game. After playing it and beating all the campaigns, I walked away very impressed. The game never really gets dull, and I just keep coming back for more. Also, the game is a “great co-op moment” machine, and I could list at least a dozen common moments in the game that are great moments in co-op. However, one of the best co-op moments of the game is one of the first ones you will encounter in the game: the Horde.
