Paintball is a leisure activity where two teams armed with a spray gun, a helmet and coloured gelatine capsules face each other. Each team tries to conquer the flag planted at the other team’s base within a limited period of time. Players hit by a capsule are eliminated. It is an exciting and very tactical game as well as an excellent team sport, offering the advantage of being a very complete experience and requiring a large variety of skills. Competition paintball can be classified either as an extreme sport (due to the high level of action) or as a mechanical sport (due to the guns used by the players to shoot the capsules).
