Vampire Crawlers overrun by Fallout's own rats, radscorpions and super mutants, with Fallout items and music from your copy.
Vampire Crawlers' dungeons, overrun by Fallout. While you crawl, the mod reads your own Fallout install and brings its real content into the run:
Solo. You need both games: Vampire Crawlers and the original Fallout. Nothing from either game is included; every player uses their own copies.
