The Nightrunner is a modern but pricy attack-class submarine designed for a large, experienced crew. The sub features advanced status screens both in the gunnery and command room as well as a silent running mode for avoiding the attention of Europa's denizens. With fabrication facilities, crew quarters and a medbay, the submarine's only weaknesses are a low cargo capacity and relatively slow speed.
