Dying Light LARP Rulebook

From the introduction:

Live Action Role Play is an immersive and interactive role playing experience. Each person who comes to an event has created a character using the system inside this rulebook. Characteristics like race, skills, and magical abilities are all chosen and put into a character sheet. This is your character on paper, but when you get to game and put on your costume, you take on the role of that character adding flesh and bones to the paper skeleton you have made. Plot is a group of people who are in charge of bringing out extras and opponents called non-player characters. These along with the other people playing characters will advance stories, create intrigue, and of course provide opportunities for combat.
