Only one may survive.
Never heard of Assassin? It's a real-time live-action game where each player is assigned another player to "kill". The game runs until only one assassin remains, victorious. You could be killed (almost) anywhere at anytime, from karaoke night, to your commute, to a shopping trip, so watch your back... You don't know who could be right around the corner.
If this sounds like fun, come along to our rules session on Tuesday. We'll be explaining everything, including a rules rundown, the various methods of "killing", and when the game starts- so be there!
