The player takes on the role of Denz de Bayle in The Cursed Crusade , a knight cursed by the Templars, who slowly succumb to hell. De Bayle's quest is to find a cure for his curse and do so with the help of Esteban Noviembre, who also bears the same curse.
The gameplay revolves around a traditional hack & slay experience, where players navigate through linear levels, killing enemies and focusing on melee combat. The curse grants de Bayle the ability to switch between the normal game world and a hellish version, which offers advantages such as increased strength, special attacks, and collectibles. However, being in the hell world drains energy, which is replenished by killing enemies.
The skill tree system allows players to unlock combo attacks for each weapon, earning victory points through completing missions and finding hidden treasures in both the normal game world and the hellish realm.
