About this game
Hand-aim every spell. Blast the gothic horde into fully-simulated pixel gore.
The horde is closing in...stack your cards and pray it isn't the blood moon this wave.
Witchtower: Spell Siege is a fast 2D action roguelite tower defense game about defending a witchtower from increasingly chaotic waves of gothic enemies.
Aim artillery spells manually, blast enemies into fully simulated pixel giblets, choose card-based upgrades between waves, and try to survive wave after wave. Every run presents different conditions and card choices, encouraging different builds and combinations.
Play solo, or team up in local co-op: one player controls the witchtower’s spellcasting with the mouse while the other fights with keyboard controls. This can be done with Steam Remote Play Together.
