Everyone is playing a role from the sheriff, deputy, outlaw and finally the renegade. Each of the roles change what is required for a win and only the sheriff is known. The rest play with their roll down and are hidden and require you to figure out who is playing each role.
You are then playing various actions that function as attacks. These can be shooting someone with a "Bang" card or other weird things that force discarding a card or getting rid of an object in play. The other players usually have defense cards that allow them to be missed or get out of the way.
So it sort of works that you are trying to figure out who is playing each roll then move on with killing folks. When the Sherif is killed the game ends which is good for the outlaws. The sheriff wants to kill all those dry outlaws as does the debuty. The renegade wants to kill all the outlaws then the deputy and finally the sheriff for a win.
It was pretty fun for our group not one complained and I would say everyone had a good time. I liked it. It would be pretty fun with a few more cards was my only complaint. Just to have more variety in the character cards. This can easily be fixed by buying the Bullet edition instead of the basic edition. The bullet seems to be pretty cheap on ebay if you get the right deal.
