Snehk's Dreamlands

I was playing half-life with someone. We had a 1v1 duel on a lan server. I claimed a base in a crushed airplane, while the other guy took the nearby bunker as his hideout. We were trying to kill eachother, and he succeeded a few times. Then it changed. I was a bank robber, and he was an agent of special forces. He hidden in the airplane, making an ambush. I shot him a few times with shotgun, to no effect.
