About
Starfab is a strategy game in the tradition of the classic browser space games, made for phone, tablet and desktop. Time runs on the server: building, flights and battles don’t wait for you to open the game.
Build mines, factories, a lab and a shipyard. Every planet has its own sun and terrain, and they change what you dig up and how much.

Send barges out to the belt’s asteroids. Asteroids run dry, and the rich ones have to be found before your neighbours find them.
You see only what your probes have scouted. The stronger your science, the more a report tells: a neighbour’s fleet, buildings, technology.
Build a fleet, attack and defend. The server resolves every battle, and you watch the replay round by round.

Team up with your neighbours: allies see each other’s bases and never attack each other. Holding the belt together is easier.

Alongside the players live empires run by the server: they build, scout, mine and fight by the same rules you do.
Planets
Anyone can see a planet’s name, type and size. Only scouting tells what lies beneath, how much sun it gets and who lives there.
