What is Fortress Under Siege?
Fortress Under Siege is a strategic tower defense game that tasks players with protecting a kingdom from an encroaching enemy conspiracy. The core gameplay revolves around managing limited resources to build fortifications, deploy troops, and command a hero on the front lines to hold back waves of attackers.
The game distinguishes itself through its focus on hero-unit synergy, where the player's active management of the commander can turn the tide of a losing battle. Unlike static tower defense titles, this game requires constant interaction with the battlefield to manage cooldowns and direct units toward incoming threats.
