Siegeheart

Siegeheart turns tower defense inside out: your keep stands at the center of the battlefield, and enemy armies pour in from every edge of the map along multiple winding roads. Garrison the ground with Ballistae that skewer whole columns, homing Arcane Spires, Oil Cauldrons that set the roads themselves ablaze, Siege Crossbows, radiant Holy Beacons that repair your walls mid-battle, and Storm Callers — then mine the roads with Rune Traps and Thorn Barricades. The keep visibly cracks, burns and crumbles as it takes damage, and heals when repaired. Fight through five fronts — the Ancient Colosseum, a rain-lashed Gothic Castle, the Floating Sky Citadel, the Crystal Fortress and the Dwarven Mountain Hold — each with its own army of animated creatures, hazards, generated soundtrack and a multi-phase boss, from the rally-crying Colossus to the phase-shifting Prime Prism and the keg-spitting Forge Mech. 45 levels, endless sieges, achievements.
