Searching NW AF. Upstairs in the tower. Suddenly hear "FRIENDLY DUDE, FRIENDLY!" Turn to see someone running back down the stairs. Scramble for mic and realise its not plugged in. "DUDE ARE YOU FRIENDLY DUDE?!" Slam F1. Other fella pokes head back up to see me waving. "Thank god dude," Was full camo'ed, gas mask, and fully modded M4 so he probably expected me to be a bandit. Cheers for not shooting me stranger.
