REASONS TO BUY Undead Citadel FOR PC


UNDEAD CITADEL is an exciting virtual reality game that immerses players in an adventure full of undead and intense combat.

Slash, stab, smash, smash, shoot or dismember enemies using your bare hands, experiencing realistic physics and immediate response.

The game offers a wide variety of weapons and potions to use during combat. With more than 60 melee weapons, such as swords, axes, war hammers and shields, as well as bows, arrows and explosives for ranged attacks, players can choose from a wide range of options.

Each weapon has its own characteristics, allowing for a strategic approach to equipment choice. In addition, slow-motion, strength and freeze potions add an extra element to the game, providing the ability to mutate the player's power and defeat the undead.
