The Tower Must Fall

The Tower Must Fall is a tower defence game in which the player builds a defensive structure by stacking modular pieces. Each run produces a different tower with its own strengths and weaknesses, and some unusual designs turn out to be workable despite appearances. Enemies attack in continuous waves, and the tower is expected to fall eventually.

Progression carries across attempts. As a tower collapses, the player unlocks dozens of new materials, weapons, resource upgrades and perks for later runs. New enemy types and bosses are introduced over time, which means a strategy that worked earlier may need to be reworked. As the range of available options grows, the engineering decisions involved in building a tower become more involved.

The game also includes multiple biomes. Each biome brings different terrain and new enemies, adding further ways for a tower to be brought down.
