Square TD
Read full descriptionHide full description
Square TD is a tower defense with a twist: enemies run a ring road around the map, and you defend your own corner. Every wave passes your zone twice — set up, hold, and don't let them reach the castle. - 8 tower types, 3 levels each — crossbows, ballistae, mortars, fire, lightning, poison, frost and watchtowers - Armor, air, invisible and boss waves — every enemy type asks for a different answer. - Synergies that matter: poison marks enemies for extra damage, frost keeps them in the kill zone, fire heats up on a held target - 40-wave campaign on three difficulties, then endless mode for records - Build, upgrade and sell while paused — think it through The first 19 waves are free. One purchase unlocks everything.
