Every location lives in its own season. Blooming valleys, scorching wastes, golden autumn and frozen fortresses — each with its own rhythm and its own foes.
Blooming valleys awaken. The first troll hordes march the winding trails — the perfect time to learn the basics of defense.
Sun-baked shores and fiery wastes. Enemies grow faster and fiercer, and the ruby towers' flame feels right at home.
Golden leaves and long dusk. Cyclopes and towering behemoths emerge in the woods — time to unleash the full power of the crystals.
Frozen fortresses and snowy peaks. The harshest trials — where frost towers slow even the most relentless.
Build and upgrade towers from a humble crystal into a towering citadel. Every crystal has its own combat style.
From blooming valleys to frozen fortresses — eight unique battlefields, each with its own paths and defense points.
Four breeds of monsters, each a distinct threat. Match your towers to the foe.
Unlockable champions of the horde — bigger, meaner and far harder to stop.
