Eerie Tower Defense is an atmospheric tower defense game where you protect a central tower from endless enemy waves.
Your goal is to survive as many waves as possible and keep the tower alive. In battle, the tower attacks automatically. Defeating enemies gives you gold, which you spend on run-based upgrades: increase damage, attack speed, survivability, and utility effects. Watch the tower’s HP, choose upgrades based on the current wave, and use active items at the right time. Between runs, spend crystals on permanent upgrades, unlock talents, and improve cards to get stronger starts in future runs. If difficulty spikes, adjust your build and rebalance your focus between damage, crowd control, and defense. The longer you survive, the better your rewards and leaderboard ranking.
