That is a lot like how my friends went down. They were travelling to Rog and ran into 2 guys, they talked, and one of my friends told them where they were headed. They trade, my friend got mags and the other guy got a water bottle. Keep note that it was 4 of us, but I had died earlier from zombies, however when I spawned, I found an AK and Makorav and all was good. While my other 3 friends, we were designated to meet at Rog, since it had such a great holding ground. Well, it just so happened to be, as they were walking, my friend in the back dropped. Bullet holes with blood spitting out of them. Quickly the other 2 ran into the safety of the castle, one guarded the stairs, the other the door. It was quiet and there was large tension. Earlier when they met up, they had told it was only 2 of them of a much larger group. One saw an opening, his head popping out of the corner. 3 bams and he's down. After a minute, the rest of the group arrives. We had thought they were bluffing, they didn't know the knee deep shit they just got themselves into and I couldn't help. At once, one guy yells out "I'M GOING TO KILL YOU ALL," they were frightened, "I'M GOING TO BLOW UP THE TOWER." Of course we didn't know how that was possible, but out of sheer luck he went down to check on my friend, and then the roof explodes. They scream, and one of them breaks their legs. Another 10 minutes go by, and the healthy one goes to the stairs and starts taking a lot of heavy fire. He takes a shot and gets knocked out. The other one, shot another guy. They were real pissed now. The castle then just fixed itself, only to be blown to bits yet again. He gets up, and gets shot and dies. The enemies rush in, look the unconscious one, and then shoot him on the head. The 40 minute struggle had ended, and they left the game, shooken, literally.
