Summary
Private Riley was a friend of Private Kappus, and in a squad that included Kappus, Private Jenkins, Private Bicenti, Private Manuel Mendoza, Corporal Lovik, and Sergeant Johnson.
He has barely any lines in the game, and is only notable for the fact that he is the first person we see successfully attacked by an Infection Form, though Kappus soon removed it, it is undoubtable that another soon found him.
