How firetag works?

Firetag is a game in which players use blank guns (firing blank cartridges), on which infrared emitters are mounted, and the shot from infrared emitter is synchronized with shots from the blank gun.
Each player wears special sensors that record hits from other players.
Thus, each active player has a blank gun with an infrared emitter and receiver sensors on the body and head. Players run various scenarios from simple team Deathmatch and Last man standing or more complicated ones: assaulting a building, rescuing hostage, using it for a safe shooting range, self-defense training, law-enforcement training.
