Valve Software has taken flack about releasing a sequel to its blockbuster zombie slayer—an innovative game that pitted four players against hordes of lightning quick undead and which was designed to be gradually augmented with new content over several years—a mere 12 months later. That said, it’s difficult to imagine franchise fans not wanting to upgrade to this sequel, which contains five new campaigns, a new play mode dubbed scavenger, a splendidly spooky New Orleans setting, and a much more satisfying story arc for its four protagonists.
