Action Trip writes: "Most likely you know all about this 'controversy'. Valve released Left 4 Dead last year and it's a huge hit. With a minimal back story, four survivors must band together to fight their way to safety through the zombie horde. Featuring the ability to play co-op against the undead or against friends in PvP mode made for an exciting and viscerally satisfying experience. When Valve came along 6 or 7 months later and announced Left 4 Dead 2 would be released only a year after the original, a good part of the fan base freaked out. "It's too soon for a sequel," they said. "Where is the all the free DLC we were promised," they asked. "It'll just be an add-on that will be sold as a full priced game," they howled (they howled indeed - Vader)."
