On your neck is an explosive device, which will explode if tampered with or if the Master of Games decides to have someone killed.
You are given a pack with food, water and a weapon. Your weapon could either be the world's most accurate flechette firing machine gun or a pot lid. It's all randomized, along with the stats of the other kids.
Along the map, weapons, food and other supplies are hidden, as well as traps. The map is divided grid by grid and will only be seen if one of you finds a map or GPS. Three random grids will become danger zones, and death is practically guaranteed there.
Along with the 40 kids, there are also two professionals. These professionals are trained and experienced killers and survivalists.
All dice rolling will be done by me.
