There are three versions for various platforms: ) The PS3/Xbox360/PC with a realistic art design ) The Wii/PS2 edition uses a stylized cartoony character design, with a greater focus on puzzle-solving ) The Nintendo DS version also uses the stylized art design, but is a squad-based strategy game where you control the original Ghostbusters instead of the Rookie.
All three follow the same storyline, but with differing level design and enemies.
