Spin a web of relays through the asteroid belt, mine minerals, generate energy and keep the pirate fleet at bay. Eight main missions, four side branches with their own twists, and an endless mode.
Everything you build must connect to your command center. Regular buildings reach only 80 m; relays span 170 m.
Miners and lasers use energy. Missiles cost minerals per shot.
Recycling refunds your investment, minus damage taken.
Asteroids hold more minerals the bigger they are, and shrink as you mine them empty.
Completing missions earns research points; spend them under Research for permanent upgrades.
Meteors show a red warning circle before they hit. Ion storms switch off solar stations for a while; energy tanks carry you through.
Ringer shields burst missiles early and weaken lasers; build THELs against them.
A building that flashes red has no energy to work: build more solar stations or energy tanks. 1–9 build Esc cancel Space pause U upgrade Shift+U upgrade all of a type Del recycle Shift+drag: select several buildings Shift+click: add or remove one M missiles on/off WASD/arrows or drag: camera
