About U.F.O. K.O. Tower Defense

U.F.O. K.O. Tower Defense puts you in charge of defending the planet from hostile craft reported in skies around the world. You deploy weapons at 20 tactical locations and can call on HQ for orbital and air support. The craft may be alien, though their origin is unconfirmed.

Defend the planet

Play through 20 levels across four environments, facing 10 different craft. You have six upgradable turrets to improve their effectiveness and two special abilities: airstrikes and orbital attacks from HQ.

Replay levels

You can revisit levels to earn three stars or reset your in-game progress. The game also has 23 Steam achievements.
