About

Rotor Defense

Features
Read full description

Rotor Defense is a tower defense game where your towers sit on three spinning rings around a central core. Enemies attack from every direction. When one side is about to break, spin the ring and bring your strongest towers around to meet them. The radar shows where the next wave will come from, so a good defense line never goes to waste. ■ ROTATE YOUR DEFENSE Towers are never stuck in place. Spin each ring left or right to focus your firepower, or turn on auto-tracking and let the rings follow the threat on their own. The whole game plays one-handed in portrait mode. ■ SEVEN TOWERS, NO MANUAL NEEDED Pulse fires homing shots. Scatter blasts crowds in a wide fan. Lance pierces everything in a straight line. Chain zaps lightning from enemy to enemy. Support them with three aura towers: Freeze slows, Plasma burns, and Ion amplifies the damage enemies take. ■ FUSE AND EVOLVE Place different towers next to each other and level them up to unlock fusions. There are twelve fusion effects to discover, and special pairs evolve into whole new towers like Glacier Lance, Burn Chain, and Ion Scatter. ■ TWENTY WAVES PER RUN Each run spans twenty waves across three acts, with bosses at waves 5, 10, 15, and 20. After key waves, pick one of three upgrade cards and steer your run. Play at 2x or 3x speed knowing the outcome stays exactly the same, only faster. ■ GROW BETWEEN RUNS Every run earns shards to invest in five research tracks, new towers, and stronger starts. Beat the final boss and unlock Chaos mode, where elites arrive early but shards pay out even more. ■ FREE TO PLAY, FAIR ADS The game is free. Ads are optional rewarded videos (continue a run, double your shards, draw a bonus card, reroll a card offer), plus one interstitial when you restart. Buy Remove Ads once and interstitials disappear for good. Every rewarded bonus is then granted automatically, no watching required. ■ PLAY ANYWHERE Fully playable offline. Progress is saved on your device. Available in English, Korean, Japanese, Simplified and Traditional Chinese, Spanish, Brazilian Portuguese, Russian, and French.
