We spoke already about the “House M.D. Larp” and its medical system: http://www.electro-larp.com/57-larp-review-house-m-d
At the last Knutepunkt, we organized a workshop to explain the game mechanics and test it on a simple case. You can now download the rules and the textbook case to do it yourself.
We hope you will enjoy the system and use it in your own games.
