It shouldn't be confused with the Paranoia Core from the web series The Underground, as it has a completely different optic. The player could portal in behind him, pick him up and carry him around for several challenges, and drop him down stairs. The Paranoia Core locks himself into an 'impenetrable' room with several turrets facing the only door and is afraid of anyone coming into get him. The Paranoia Core is a reference to an early development core for Portal 2, as the basis for Wheatley. The Paranoia Core is only available as a Bounty after gaining all the others (Sam's Banjo, Claptrap's VGA Award, Brock's ORB, Ash's Necronomicon ex Mortis).
