Heresy World is an unofficial hack of Dungeon World that ports it over to the Warhammer 40k universe with the intention of having players play a game similar to Dark Heresy. That is, players play Acolytes of an Inquisitor who must root out heresy in the Imperium of man.
Heresy World's main mechanics are based on Dungeon World with other mechanics and great deal of the fluff being taken from the Dark Heresy 1st and 2nd editions by Fantasy Flight Games.

The code I've written for the website is mine and you can't use it for anything.
