Bastion Realms

Bastion Realms is a complete 3D tower defense campaign in the browser. Hold the line across five distinct realms — the wild Verdant Hollow, the erupting Cinder Wastes, the frozen Frostmaw Expanse, the haunted Sunken Ruins, and the reality-bending Astral Isles — each with its own enemies, music, environmental hazards, and boss. Build and upgrade 8 distinct towers (bolts, snipers, chain lightning, fire, frost, poison, cannons, and war banners), read each wave's composition, and counter armored, warded, flying, regenerating, and shielded enemies. 45 handcrafted-feel levels with unique winding paths, elite waves, and five multi-phase bosses that summon reinforcements, raise shields, and phase out of harm. Earn stars, unlock achievements, and push your record in per-realm Endless mode.
