Bethesda Softworks is getting ready to release the fourth mini-expansion to their best selling open world RPG Fallout 3. Today the game's official web site has added six new screenshots from the DLC expansion, Point Lookout, along with an extensive developer's diary on the expansion

The dev diary talks about how the creative team used the real swamp and marsh land region around the real Point Lookout, MD as their basis for the setting of the expansion along with trying out some new artisitic styles and putting more of a dense setting than the original game's Capital Wasteland. The expansion will be available for purhase and download via Games for Windows Live on June 23.
