From the Steam store

You're an ant with a very demanding queen, and you will protect her at all costs!

In Formic Fortress, prepare to face a relentless assault of insects coming to get your queen. Start fresh on every run. Seal the entrances with blocks, or hurl anything you can find at these nasty buggers. Survive the waves, grab shiny power-ups, and team up with a friend in local co-op to bolster your numbers and ensure your colony's survival... or prepare to get scolded by Her Majesty!

Strength in numbers!

Hand that second controller to your friend and have them join the fight against those pesky bugs, or make use of Steam Remote Play Together and keep your couch to yourself. With up to 2 players in local co-op, your enemies don't stand a chance!

Strategy meets chaos!

Wield building blocks as weapons! Will you add that leaf to the hill, fortifying the entrance to the queen, or will you throw it at your enemies? The choice is yours, but you better make it fast!

A fresh playstyle every time!

Choose from a variety of unique power-ups after every wave to customize your playstyle for the run. Will the microplastics in your soda cap poison your foes, or are you more the leaf shuriken type? You decide. With every run, create a fresh new build that will have these harassing bugs shaking in their... bug boots.

A living, breathing world!

Experience the trials of nature through a full day/night cycle and 4 distinct seasons. Fight while the sun is up and prepare for the next wave under the moonlight. Each season brings unique environmental challenges and types of blocks to master.
