Mark Ryan

"Hey, you're that new guy headed for the old comm's center, right? You'd better hustle up, pal."

- Mark Ryan, upon meeting the Marine

Mark B. Ryan (Identification Number: 9368-41) was a security officer assigned to the Mars City Underground. He guarded the airlock connecting it and the abandoned comm facility. After being told by T. Brooks that Doomguy was coming ahead of time, Ryan directed Doomguy towards the comm facility and assuaged his fears about having to walk around on the surface of Mars by reminding him that his suit carried plenty of oxygen. Unfortunately, at the start of the invasion, Ryan was killed by a zombie, who dragged him away and started eating him before Doomguy returned and promptly killed it.

The player can pick up Ryan's PDA if they shoot him when they first see him. He doesn't appear in the Xbox port, although his PDA can be found.

Got a new guy on the way (11-15-2145)
Hey Mark,

''We had a new marine just come through the security checkpoint. He's gonna check out the old comm building for that missing scientist. Can you make sure he doesn't get lost... last thing we need is another missing person.''

Thanks Bro
