The final level is devoted to a unique boss fight. The player will face weak minions (which change based on the episode), plus occasional sub-bosses which will try to escape into town. Single player takes the form of a 'Story' mode divided into five episodes and fifteen linear levels. Features new dialogue from the original voice actors on the show.
The player takes control of Kyle, Cartman, Kenny and Stan to fight through the town in a first-person perspective. A comet is heading toward South Park, causing many of the enemies from early seasons of the shows (including cows, aliens, and clones) to rise up and attack.
