About this game
Citadel Siege is a strategic tower defense game where your mission is simple — stop the enemy from reaching your citadel. Deploy a variety of unique warriors along enemy paths to intercept and destroy incoming waves.
Each unit plays a crucial role: some excel in melee combat, others attack from range, while support units poison enemies or strengthen nearby allies.
But beware — your enemies are not mindless! Some will rush through your lines with speed, while others split into even more dangerous forms upon defeat.
To survive, you must build barriers, control the battlefield, and plan your troop placement with precision. Outsmart the enemy, hold the line, and defend the heart of your kingdom!
