Defend one isometric floating island against a nonstop enemy stream. Build Archer, Hunter, Ice, and Catapult towers, upgrade them to Lv5, and survive as Threat Level rises over time. The swarm grows denser with dynamic active-enemy limits, faster spawn intervals, visible monster levels, elite enemies, rotating bosses, survival rewards, and local best threat, kill, and run-time records.
