About the Game

You find yourself on a small planet with limited resources. Space is a dangerous place and you will need to build your planet defences before the invaders arrive. Try to keep your planet from being conquered by waves of lovecraftian enemies. Build a small spacecraft and venture into space yourself to capture other planets in the Solar System.

Your spacecraft can be equipped with diverse defences and upgrades. Flying, repairing and equipping your spacecraft will cost resources. Maintaining your planet(s) defences will also cost resources. Even mining your resources will cost resources.

The aim of the game is to survive the invaders and conquer all the planets in the Solar system. You will have to be strategic about acquiring resources, maintaining defences and flying and equipping your spacecraft.


"Space Mission Overdrive sounds just like the coin-eating-eye-burning-bright-light-flashing-lazor-blaster-starship game I was looking for"
