About Cartonfall: Fortress

Cartonfall: Fortress is a survival game about building a cardboard-box base and defending it from waves of enemies. You construct towers, castles, cottages or bunkers, set traps and craft weapons from materials you collect.

Build your base

Maps are randomized, bringing different challenges each playthrough. You can set up a production line to generate a steady supply of resources for expanding your base. After each wave you defeat, you can upgrade the base and expand your arsenal.

Set traps

Enemies attack from all sides. You can lure them into traps that set them on fire, shock them with electricity, freeze them or blow them up. Plan your defenses and try different trap combinations; each enemy type calls for a different strategy.

Craft weapons

Collect tubes, cans, wings, batteries and firecrackers to make weapons such as flamethrowers, freezing grenades and exploding planes. Each weapon works differently and has a different effect on enemies.
