"Monster Lab puts you in the lab of a mad scientist, and gives you the opportunity to create your own Frankenstein monsters. There are three schools of science (Mechanical, Biological, Alchemical) and you piece together monsters from bizarre and menacing heads, arms, legs and torsos.
Attach that mechanical buzz saw arm to that fire breathing skull head! Who says you can't? You are the fourth member of a prestigious science society, working to take down a member who has gone rogue and violently mad, and you can do whatever you please!"
