World War Z doesn’t have an original bone in its body, but I think that’s okay, because it’s a shameless Left 4 Dead tribute in a world that’s been waiting for a sequel for a decade now. As with its primary inspiration, Saber Interactive have some big free updates planned for the game, including new missions, difficulty levels, game modes and features. I admit that I’m a little surprised at how successful the game has been, considering how little interest people seemed to have in the lead-up to launch, but it’s good to see the studio committing to a protracted zombie siege.
