The 3rd and final bit of Fallout 3 DLC is on the way for the 360 and PC versions. Bethesda just released the first screens as well as a release date.
The DLC comes out on May 5 and will change the ending of the game, in order to make it “never-ending”. Because, y’know, who doesn’t like open ended games these days?
The add-on will also raise the level cap to 30 and contain new weapons, 2 of which include the Tesla Cannon and the Heavy Incinerator.
