Build absurd towers!

Stack modular tower pieces to create strange and unstable defences. Every run produces a different tower and every tower has different strengths and weaknesses.

Survive escalating waves!

The enemy won't let up and throw wave after wave at you. Dealt with the grunts? Here come archers. Dealt with the archers? Here come ultra fast kamikaze bats. The tower will fall and you will have to adapt. 

Grow your toolkit and power - permanently!

Grow your power with every run by unlocking dozens of upgrades. Unlock materials and weapons, improve their durability and power, increase your resource output and rewards, you get the idea!
