E. Grafton

"Welcome to the unit, I'll see you around. Hope you don't get too crazy here, like the others, hehehe!"

- E. Grafton

E. Grafton is a marine on patrol in Mars City patrolling the area around Marine Command. He wears a helmet, heavy armor, and wields a standard issue machine gun.

Unlike most other characters the player meets throughout the game, he warmly welcomes the player to his job with a slight chuckle when he talks to him, but then tells him he has to do his job. After the first invasion as the Doomguy approaches the console that is requesting an uplink, Grafton can be found on the three stairs dead. A spot of blood on his upper body implies that he met his unfortunate fate from a gunshot. He was either killed by a zombified marine or was turned into a zombie and was shot.
