The Cursed Crusade follows Denz de Bayle, a knight afflicted with a Templar curse that slowly drives him to hell. His quest for a cure leads him to join crusaders, including Esteban Noviembre, who shares the same affliction. Together, they must fight against another cursed group with sinister plans.
The gameplay revolves around traditional hack & slay elements, with players navigating linear levels and battling enemies in melee combat. The curse allows de Bayle to switch between the normal game world and a hellish realm, offering advantages such as increased strength and special attacks. However, time spent in hell drains his energy, which is replenished by killing enemies. Players can unlock new combo attacks through skill trees, accessible via victory points earned through mission completion and collecting hidden treasures.
