About This Game

In Stack Gun Heroes you defend a portal against hordes of infected robots. You'll design guns, run on walls, collect superpowers, and earn the love of countless adoring fans in a universe teeming with robotic life.

Invent guns

You can stack mods on your gun to change the bullets it shoots.

Stacking is deep. Combine any mods you want for unique effects.

You can even stack dozens of mods at once to create an unbelievably awesome superweapon!

Build a massive ammo factory

You build ammo factories by shooting them into existence block by block.

Placement is crucial. Each block is a machine that processes loot, and good layouts work more efficiently.

    Key Features

  • Gun improvisation: Instantly invent guns in the middle of combat.
  • Over 30 types of gun mods: Make lightning lassos, rapid fire nukes, guns that shoot guns, and more. One alpha tester now flies everywhere after inventing a gun that lets him soar through the air.
  • Base building: Shoot walls onto your base with the Stack Gun and build giant factories that process your loot.
  • Build a collection of randomly generated superpowers: Summon robots, call nukes from the sun, teleport enemies into the ocean and more.
  • Play alone or with friends: Best with 1-4 players. Solo, co-op, and PVP.
  • Lots of game modes: Defense against hordes of enemies, target challenges, obstacle courses, pvp deathmatch, racing, and more.
  • Walljumps and wallslides: Build up momentum and slam into enemies for massive damage.
  • No max power level: Find more and more powerful mods forever. Achieve god-like status as the rules of the game start to bend and break under your immense power.
  • No max difficulty: There are always tougher missions with better rewards. We can't predict how far players will get.

After 6 years and over 14,000 hours working on this project it's almost ready. Stack Gun Heroes is my dream game. Hopefully it's yours too!
