About Citadel Siege 2

Citadel Siege 2 is a tactical tower defense game in which you build and adapt defenses to stop waves of enemies from reaching your citadel. Enemies attack in larger numbers and use new tactics, so you must adjust your strategy as the battlefield changes with each wave.

Defend the citadel

Place towers and defenders, block paths and funnel enemies into traps. Some enemies rush forward at high speed, some split into more dangerous forms when destroyed, and others resist or ignore your attacks. Wider paths and more complex enemy movement add further challenges.

Defenders and enemies

You can unlock new defenders, including fire-wielding towers that incinerate groups of enemies, poison traps that slowly wear down even the toughest foes, and warriors who fight as melee fighters, ranged archers or support units that enhance your strategy. The game features smarter, tougher enemies with unique mechanics, and its tactical gameplay evolves with each level.

Visual atmosphere

The game has enhanced visuals and a darker, more intense atmosphere.
