Hwacha Fortress
Command a towering Joseon wheeled siege fortress across a 10-minute battlefield—ramming enemy battering carts and watchtowers while unleashing Singijeon rocket arrows, bronze Chongtong cannons, and Bigyeokjincheonroe bombs.
Key Features
- Steam Overdrive & Hull Ramming: Keeping your fortress rolling at full speed builds Steam Overdrive, boosting all siege turret damage by up to 45%. Smaller enemy carts, wooden watchtowers, supply wagons, and raider camps can be crushed outright by ramming them with your hull.
- 4-Stage Fortress Expansion: Collect scrap iron and Joseon coins to expand your chassis through four tiers—from a Small Cart Castle to the colossal Taesan Moving Citadel—unlocking up to 6 active turret slots.
- 12 Joseon Siege Modules & Masterworks: Mount 12 historical and mythic siege weapons—including the Singijeon Hwacha, Cheonja Cannon, Thunder Bomb Trebuchet, Flame Wagon, Iron Turtle Ram, and Black-Powder Mine Layer—and evolve each max-level module into its Masterwork form.
- 3 Fortress Hulls & Colossal Bosses: Unlock the Hwacha Fortress, Land Turtle Ship, and Thunder Siege Keep, and clash against massive enemy fortresses at 3, 6, and 10 minutes—culminating in the Emperor Citadel.
- Daily Sortie: Compete once a day under a shared calendar seed where every commander faces the exact same chassis and enemy wave schedule.
How to Use
- Press and drag anywhere (or use WASD / arrow keys) to steer your wheeled fortress.
- Turrets aim and fire automatically; stay in motion to maintain your Steam Overdrive damage bonus.
- Ram smaller enemy carts and wooden outposts to harvest scrap and supply crates.
- Choose a new siege module or hull upgrade on each level-up and defeat the 10-minute Emperor Citadel.
