Who needs new games when you can just download new content for your old ones? We'd already heard about the incoming wave of downloadable content for Fallout 3 and Left 4 Dead, but now, we know when it's coming out. Well, mostly.
According to Eurogamer, Bethesda has officially announced that its next Fallout 3 DLC episode—titled The Pitt—will come out on March 24. Just like Operation Anchorage, this episode will cost 800 Microsoft points, or 10 real-world dollars. The Pitt will allow you to explore the ruins of Pittsburgh, where Eurogamer says you'll be "embroiled in a dispute between slaves and their owners."
As for Left 4 Dead, IGN has word that the first DLC bundle for Valve's co-op zombie shooter will be out by April 21. The article actually mentions a "March or April" release time frame, but it also points out that a Critics Choice Edition of Left 4 Dead with the DLC and all updates is scheduled for an April 21 console release. Evidently, the DLC will be out by then.
The Left 4 Dead DLC will be available free of charge to both PC and Xbox 360 users, and it will bring two additions. First, folks will be able to play the game's other two campaigns, Dead Air and Death Toll, in the competitive Versus mode. Also, Valve will include a new Survival mode together with a new "Lighthouse" map. According to IGN, Survival games pit up to three players against a never-ending horde of zombies for relatively brief games, awarding medals for the longest survival times. Don't expect it to be easy, though—none of Valve's own designers have reportedly made it past the 10-minute mark. (Thanks to Shacknews for the links.)
