Oh man. I love this xpac (comes with the bullet!) if only because of the titular "fistful of cards" event.
It completely turns games around, you can be completely losing, and this will give you a chance at a comeback. On the other hand, it can be really frustrating, so sometimes we choose to play without it. Either way, there are plenty of cool characters and events in this xpac, I would highly recommend it if you already like BANG!
This is another mini-expansion for Bang! in a style very similar to High Noon. A Fist Full of Cards introduces global events that apply to all players and make the game more chaotic and random. It also makes it feel fresh and exciting, and even more fun. I definately recommend this expansion to anyone wanting to breathe even more life into Bang!
