About this game
Hisar · Fortress Defense is a browser-based low-poly 3D tower defense game built with Three.js in a single index.html file, free to play with no install and available in Turkish and English on desktop and mobile. An army advances along two roads toward a seaside fortress; the player builds towers on stone pads and upgrades them to hold out for 15 waves, then continues in endless mode. It offers three tower types with three levels each (Archer Tower, Cannon Bastion, Tar Cauldron), four enemy types including a Battering Ram boss every fifth wave, per-tower targeting modes, a 70% sell refund, early-wave calling for bonus gold, and 1x/2x/3x speed. Progress is saved after each cleared wave with a Continue option, and there is a pause menu, settings (volume, language, quality, fullscreen), an end screen with stats, and Web Audio music and sound effects. The repository is MIT licensed.
