S. Holmes

"You need to report to Sergeant Kelly ASAP. He's in Command HQ."

- S. Holmes

S. Holmes was a marine guard at the Mars City Marine Command. He was stationed there by order of Sergeant Kelly to guard the HQ. When the marine gets there, Holmes warns him that "If you don't get to the HQ, Sergeant Kelly will have your ass".

Holmes was in Mars City when the Delta Labs Teleporter failed and created a gateway to Hell. Holmes lost his helmet during combat against the forces of Hell and the zombified personnel. He can be found when the Doomguy arrives at Marine HQ, where he is strangled to death by a zombie.

Trivia

 * His name refers to Activision production coordinator for DOOM 3, Steve Holmes.
 * His helmet can be seen on the floor between the HQ and the Infirmary.
 * It is impossible to save him. Stepping into the hallway triggers a zombie to appear and strangle him. Using  allows you to enter the hallway without triggering the zombie, but even if you turn it off, you can still walk through him as though he is a ghost. Further, clicking him does nothing (you cannot talk to him).
