Royal Siege

Stone walls already stand under siege. In Royal Siege, a lone defender holds the fortress against an invading army bent on smashing through the ramparts and flooding the realm. Enemy waves crash into the castle line across a string of battlefields, and the road ahead stretches from medieval Rome to post-apocalyptic wastelands. Goblins crowd the approach. Trolls push in behind them. Fire-breathing dragons and other bosses press the attack as the kingdom waits behind the gates.

How to play?

Raise the crossbow and fire into the advancing ranks before they break the walls, then pick one of three bonuses between assaults to raise damage, fire rate, or another stat tied to your defense. Gold coins drop after victories. Spend them on upgrades or buy fresh weapons, expanding the armory from basic shots to catapults, cannons, and heavy machine guns. At scattered moments, colored targets appear on the battlefield; shoot them to trigger natural disasters that hit the enemy line. Extra projectile effects also enter the fight, adding fire, ice, or electricity to each shot.
