Your remote deep space station is under attack! By space aliens! Your only hope is to match their ferocity with your laser cannon skills, but laser cannons don't run on good intentions. You'll need to take your lander deep into the mines of your moon to gather supplies, then trade those supplies with other bases across a perilous asteroid belt.

- Your lander needs fuel
- Your cannon needs energy
- Your base needs less space aliens!
- Traders can get you out of any resource jam
- Shoot all the space aliens to level up
- If the invaders overrun you, the game is over
