J-5 is the callsign of an ASD that can be activated by the player in "Celerium". There is a career record challenge for keeping J-5 alive until the point where the player gets the Celerium. If J-5 is still active at the point of Erik Breighner's death, once the player turns around after he is shot, they will see that the ASD was temporarily disabled by an EMP so that it would not interfere.
- J-5's callsign may be a reference to the 1986 film Short Circuit, a movie about a robot named Johnny Five that gains sentience.
