About Citadel Siege

Citadel Siege is a strategic tower defense game where you deploy warriors along enemy paths to stop waves from reaching your citadel. You place troops carefully, build barriers and control the battlefield to defend the heart of your kingdom.

Units and enemies

Warriors fill different roles: some fight in melee, others attack from range, and support units poison enemies or strengthen nearby allies. Units have active and passive abilities. Enemy waves include fast attackers and enemies that split into more dangerous forms when defeated.

Battles and environments

You face increasingly tough challenges across multiple environments. Walls and other structures let you alter enemy movement as you plan where to place your troops.
