Sand Bastion

Welcome to the sunny shore! In this vibrant 3D Tower Defense strategy game, you become the master architect of a coastal fortress and defend the beach against playful sea invaders.

The secret to victory is strategic maze building. Do not rely on simple straight lines: raise walls of packed sand to force enemy waves into long, winding corridors under heavy crossfire. Dynamic pathfinding instantly recalculates enemy routes with every new wall you place.

Assemble an impenetrable defense using shell cannons, water sprinklers, solar prisms, and coconut mortars. Stand firm against swift crabs, nimble starfish, armored hermits, diving seagulls, and gargantuan Kraken bosses threatening to wash your castle away.

Call upon powerful abilities — scorching solar beams, swirling whirlpools, and loyal crab patrols. Conquer 50 campaign levels or test your endurance in endless survival mode. Collect pearls to unlock permanent talents in the Workshop!
