A simple game type I play with friends.
HITMEN
We played it with around 8-10 people in my friends large yard.
Da rules:
Everyone has a number, say 1-10 for 10 people. There are also cards with these numbers. Everyone picks a random card and must shoot whoever is on that card. If you kill that person, you grab their card and count to 5, then look at it and go after the person on that card. If you get your own card number, you can go after anyone you want, and loot the card. This results in hunger games type scenarios, with shaky alliances, betrayal and the knowledge that eventually you will be at odds with your very own teammates if you choose to ally.
