TowerMadness is a 3D tower defense strategy game for iOS and Android, developed by Limbic Software.

UFOs drop invading aliens on landing pads and the waves of enemies make their way to the base to abduct the sheep.

There are two game modes: Normal and Endless, in which both contain maps with easy, medium, hard, or madness difficulties to choose from.

This mode also includes a Sandbox option, which starts off the player with 10,000 coins and a speed boost of adding and upgrading towers before sending the endless waves of aliens.
