During an airsoft game limited to pistols and pump-action shotguns on the 14th, I managed to sneak into the back of a derilict sawmill part of the field and into the pitch black tools storage corridor. There I waited to see if anyone on the other team above had heard me. Heard someone back at my entry point shouting to someone above not to shoot down through holes in the floor, concluded that my team mate who held the entry had been eliminated.
I waited in the dark, pistol ready and spotted the one who shouted making his way through the debris diagonally across from me, having walked through the main hall paralell to my hiding place. I trailed him with my pistol for a couple of heartbeats, then fired with a satisfying grunt and a 'tagged' from my target!
Half a minute later, another of his teammates followed his trail to see where he was shot from and try flushing me out... he never saw my single 'killshot' either until it was too late!
