Each battle takes place in an arena based on the first three Metal Gear Solid games: Inside a building from Shadow Moses Island, inside the Big Shell (Strut C), and a camp in Tselinoyarsk. The terrain from each is always the same, so knowing the map is important when forming a strategy, as fire extinguishers and oil drums can cause extra damage and status ailments, and the watch tower from Tselinoyarsk can be used to avoid most attacks from Vamp and The Boss.
