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.

He welcomes the player to his job when he talks to him, but then tells him he has to do his job. It is not certain whether or not he was killed during the invasion, but is very likely that he was either killed, or turned into a zombie.
