Author's note:

The first ever quadrilogy in South Park Gaming is complete with Cartman's Adventure 4! Playing once again as Cartman, you discover that a new insane scientist by the name of Professor D. has stumbled upon Dr. Doom's research, and is hell-bent on carrying out Dr. Doom's original wishes.

It's up to you, and you alone, to make your way to Professor D. and stop him before it's too late! With amazing graphics, an advanced save engine and tons of hidden extras to unlock, Cartman's Adventure 4 is a must-play game, and is easily my best currently released game to date. Highly recommended.
