Riley

Private Riley was a friend of Private Kappus, and was in the same squad as Kappus, Privates Jenkins, Bisenti, Manuel Mendoza, Corporal Lovik, and Staff Sergeant Avery Johnson. He was killed by a Flood infection form.

He barely has any lines in the game, save for a few groans and yells, and is only notable for the fact that he is the first Human successfully attacked by an Infection Form. When he was attacked by the creatures, Private Kappus attempted to pull it off of him. Though the Infection Form is soon removed by Kappus, it is undoubtedly assumed that another soon found him.

Trivia

 * It is possible that he was the Private that fell through the door when the Master Chief opened the door in the containment facility where Johnson's squad was infected.
 * On very rare occasions the player can see an assault rifle underneath Riley while the marine is trying to pull the infection form off him, which is strange, since Riley seems to be holding an assault rifle.
