Tower defense

Saucer Siege

Medieval towers versus flying saucers. Hold the valley!

Created by Gowtham · Published by models.codelove.in

A 3D tower defense where ballistas, cannons, catapults and turrets defend a medieval valley from waves of UFOs. Plan your build along the winding road, upgrade towers into tall keeps, and shoot down beam saucers before they freeze your defences. Three maps, mothership bosses every five waves.

How to play

1Flying saucers follow the road to your crystal keep. Each one that reaches it costs lives — lose them all and the valley falls.
2Tap an empty tile beside the road, then pick a tower. Or press 1–4 first and click tiles to build quickly.
3Ballista: fast bolts. Cannon: splash. Catapult: huge range and splash, slow. Turret: rapid fire — great on scouts, weak against armour.
4Select a tower to upgrade it (each level adds a floor) or sell it for 70% back. Tap a saucer to make every tower in range focus on it.
5Purple beam saucers freeze the nearest tower with a tractor beam — shoot them down first to free it.
6A mothership arrives every fifth wave. Call waves early with Space for bonus gold.
