A 3D real-time tower defense survival game inspired by Age of Empires II's "Art of Defence" custom campaign. Build a medieval stronghold from a single resource - gold - and defend it through minutes of escalating siege.
9 buildings - Arrow Towers, Bombards, Castles, Walls, Markets, Town Centers, Outposts, and the University tech tree
13 enemy types - from Swarmers to Battering Rams that smash through stone
7 unique maps - moats, forests, river crossings, canyons, marshlands
Multiple difficulty modes - With tuned starting gold and enemy scaling to match your playstyle and experience
7 research trees, 21 upgrades - meaningful synergies that reshape your strategy
27 Steam achievements - including challenge runs (no walls, arrow-only, no research, perfect defense)
Mouse and keyboard support, partial controller support
Place Outposts to buff nearby towers. Stack Reinforced Walls research with Fortified Foundations for 4.5x wall HP. Farm enemies with Bounty research. Or rush a Castle and hope for the best. Every match is a series of compounding economic and defensive choices.
Survive the full timer. Lose all your Town Centers and Castles, and the realm falls.
