About the game
Formic Fortress is a party-style tower defense game built for local co-op play, adding in some roguelike touches. Players scavenge and hurl blocks to build up an anthill and hold off waves of invading bugs. The goal is to keep the queen safe and outlast the swarm, backed by ammo upgrades that reset with every new run. Tricade Interactive both developed and published the game, available since 2026.
