As a brave Knight, it is up to you to repel 50 waves of orcs, ogres and other terrors from the fort. Hold them off at the barricades, or fight them toe to toe inside the castle. Build buildings to fortify your position, unlock new equipment, or create friendly soldier training options.
Use WASD to move, mouse button to swing weapon. Press space bar to pause game and to view the screens for equipment, units, buildings and skills. The game saves your progress every 5 waves. You keep your level and skills from game to game, so you can start a brand new game with all your skills intact from wave 1.
