In an amazing throwback to the first episode of the show. your character gets abducted by aliens early in the game, and you guessed it, has an unpleasant encounter with a probe. The scene would have been funny enough just with the player character having to escape the ship, but
Randy Marsh and Mr. Slave are victims of the aliens as well. Actually, Randy is the victim, while Slave, the hilarious caricature, seems to be having the time of his life, asking the aliens administering the procedure: "Oh Jesus, Jesus Christ, Oh! Can we try the big silver one again?"
It wouldn't be a proper South Park game without a couple of appearances by Mr. Slave and some alien rectal exploration technology.
