Sooooooo, I am stuck on the roof of the NW Airfield, just got ROCKED by zombies, managed to get away and take cover. But I am low on blood, ammo and other stuff. I need a blood transfusion really, and a chance to get the hell out of the Airfield, that place blows. Pretty much have to go at night, and when I do, zombies glitch spawned on me on two different servers. I am pretty trapped, any help would be appreciated.
