The Advanced Unitologist RIG, also called the Tank Suit, is a suit that can be worn by Isaac Clarke in Dead Space. It is only available through purchasing the Tank Pack Downloadable Content. The Tank Suit has a 60% damage resistance rating, far more than any other available suit. Like all DLC suits it has the full 25 inventory slots. The undersuit is black with gray armor plating with Unitology symbols etched onto it, and the helmet's visor glows a dim white light.
