'Fight 4 Your Friends' Humble Bundle Includes Back 4 Blood, Zombie Army 4, and More for $15
Humble Bundles regularly bundle a variety of games together on the cheap, though only for a limited time. The latest Humble Bundle, "Fight 4 Your Friends," is of particular interest since it contains nothing but co-op games! Players can get 4 great games for $10 or donate $15 to get the full six games, including Back 4 Blood and Zombie Army 4. Having played 5 out of the 6 bundled games, I can assure you that this is a great value, especially if you can get a friend to grab the bundle for some cooperative multiplayer!
