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.

I find it extremely puzzling that the "Conquest" mode is not part of the core game... :/
