CLAIM YOUR DESTINY WITH THE POWER OF THE DARK GODS!
Broken Chains is an introductory adventure for the Black Crusade roleplaying game. For centuries, the starship Chains of Judgement served the Inquisition of the Imperium, transporting the most dangerous renegades to their doom. Now, however, the Chains of Judgement is lost in the warp. The imprisoned renegades have one chance to escape their fate and take the first steps towards leading a Black Crusade.
Broken Chains is an introduction to black adventures and eternal damnation in the grim darkness of the far future. Welcome to Warhammer 40,000 Roleplay.
A set of basic rules are included to help players and Game Masters become familiar with the Black Crusade roleplaying game.
This free booklet gives you a taste of the exciting new roleplaying game from award winning publisher Fantasy Flight Games. Black Crusade will be available late summer 2011.
