Stack Gun Heroes

A hybrid FPS/Factory game great for fans of Borderlands, Factorio, Satisfactory, Magicka, Noita, and others.



Invent incredible weapons using a system that is extremely deep and easy to learn. Combine any gun parts to create gravity bombs, lightning lassos, nuclear warhead machine guns, and more. Your weapon design is crucial to your effectiveness as a robotic soldier, and each part you add will drastically change how it works.



The armory is a Hero-class robot's primary source of power. It processes loot you get on missions into ammo and upgrades. How efficiently it works is up to you. Will you turn your armory into a complex automated monster of a weapons factory? Or focus on a larger number of lucrative combat missions instead?


Show off your inventions by saving entire planets with them. Want to use your armory online? No problem, bring the entire building complex with you into online multiplayer. Do tougher missions with friends for even better rewards, and customize your weapons to synergize together.



Each mission pits you against a small army of enemies with randomly stacked guns. How will you handle enemies that call in orbital bombs with every bullet? Or fire turrets that push you back at mach 1? With a gun you can redesign on the fly, you are as powerful as you are creative. Get Stacking!
