Regicide is a brutal third-party campaign for Forbidden Psalm, the 28mm miniature-agnostic wargame. Up to two players can combine their efforts or prey on each other in order to survive - all while an undead horde marches on killing everything in its path. This campaign is also compatible with the In The Footsteps of the Mad Wizard expansion.

Regicide is not a stand-alone game, and a copy of Forbidden Psalm is required to play.
