An intersting story-based action/espionage game made in 2000, South Park Espionage
 was always in the shadow of South Park Y Project (for a good reason, though). Playing as Stan, you discover that Mephisto has made evil clones of various kids from South Park, who he's employed to kill intruders on site. After going to find the truth, Stan uncovers a more deadly plot that could very well threaten the Earth as we know it. Offers several different styles of gameplay through 9 different levels, though topped in every way by its sequel.
