The ultimate Gamblers game, Russian Roullette with 5 bullets

This should definately be a side quest or some small random encounter. You arrive in a dark room where the only light comes from a lone lamp shade hovering over the table. The smell of scotch, jet, and tobacco rise from the center of the room. You see four other men around a round poker dealing tabletop. One is wearing a green shade cap and is the dealer. n the center of the table is a .357 revolver. The man in the door 'persuades' you in to the dark room. You think to yourself:
I really shouldn't have wandered into this narrow alleyway . The green capped man with a cigar jutting from his mouth invites you over with a wave of his hand. The other men have looks of despair or calm collected fruition, and glints of mania. The man explains the game, and the outcome. It begins with the man on your left in a counterclockwise rotation of turns. He puts the revolver to his head clinching his teeth, Pulls back the hammer and shoots. There is a bang and the mans head hits the table with a thud blood exiting the wound.
Then the pistol is given to you, you look up at the surrounding faces, some glare back with questioning looks. you pop open the cylinder to count the rounds, '4 left.' There were still 3 men at the table (not counting yourself) and the doorman. You point the barrel to your head, then you decide you got a better chance fighting your way out than accepting your fate and proceed to a holdout gunfight with the remaining men. Wether you made it out alive is up to you.
