NERO International is a live action role-playing game (or LARP) played in the United States and Canada. NERO stands for "New England Roleplaying Organization", but this is actually somewhat of a misnomer, as the game has expanded beyond its original New England roots. It is a "boffer" style LARP that uses simulated combat with padded weapons. At a NERO game, players gather at campsites on weekends that local chapters designate as events. Most chapters run an average of six to ten events a year. A group of staff members write the plot and story for the event, while a cast of volunteer NPCs play the roles of monsters and townspeople, helping to sustain the illusion that the campsite in the woods is actually a medieval-fantasy town. The heroes of the event (or PCs), play the part of adventurers, nobility, and various ne''er-do-wells that are spending the weekend in the town. Every chapter of NERO operates in the same game world, Tyrra, on the same in-game continent, Avalon.
