The Biosystems Lab is a location and plot element in Phantasy Star 2. It is the system responsible for creating and breeding the creatures on Mota. It is the ultimate destination of Rolf's first task - retrieve the data recorder for the Lab in order to learn why it has been producing dangerous creatures. The basement level in particular is very dangerous. It is full of strong biomonsters and, additionally, the floor has many acid spills which cannot be avoided, resulting in damage to all members of the party.
