"Semper Fi? That's Marines. I'm airforce," Nolan snapped. "You better get that one right or I will have to take you out." He smiled, starting to laugh a bit. "Alright, I'll be pissy later. Look, Bob is running out of power. He's disabled scan and vocal so we're blind for the most part and running out of time." Nolan pointed down the stairs. "I think our way out is empty, but only what we can see. The rest of the way seems shut. Since we just got ammo, it's not a good idea to start wasting it, right? I'd say our best route is back the way we came, now."
