Bethesda has announced it will deliver the fourth expansion to its popular post apocalyptic adventure game, Fallout 3, later this month. Dubbed Point Lookout, the extra content will put players in a radioactive swampland along the coast of Maryland where they will encounter new mutants, allies, and weapons as they try to unravel the mysteries of this town. As usual, there will be choices to be made, which will open up a whole new series of missions and possibilities.

Point Lookout will be released on Xbox Live Arcade and Games for Windows on June 23, priced at 800 Microsoft Points ($10), with a PlayStation 3 release later on. Bethesda is calling this their “most open-ended DLC yet,” and while it won't raise the game's level cap at all, it is intended to be significantly challenging even for high-level players. Hopefully, they’ll sort out the issues that marred previous DLC releases as well.
