La Tumba is a freeform larp for 6-13 players, with no GM.
When cartel gangsters stumble upon an ancient shaft tomb outside of San José del Carmen in Jalisco state, the townspeople who have sworn for generations to protect it find themselves in a bind. They can't exactly confront los Narcos, but they can't allow the tomb to be desecrated, either. Moral, ethical and spiritual dilemmas abound, and all is not precisely as it seems.
This game uses cards which are available for the cost of printing from DrivethruCards.
Note: the MP3 file listed in the "requirements" isn't actually required. If you'd like, try streaming narcocorrido music for the first half of your game and nature sounds for the second half.
