A strategic management game, best described as a sci-fi tower defence game with moving spaceships and configurable units. Design your own ships from a series of hulls+modular components, group the ships into a fleet, give the fleet orders and positions and then watch it engage in OTT gratuitous space battles against enemy fleets.
These are screenshots from a new race of ships for GSB, called 'The Nomads'. They are a long-lived, ancient travelling species hunting other, lesser, younger species for their own amusement.
