What's paintball ?
Paintball is a sport in which players eliminate opponents by hitting them with pellets containing paint (referred to as a "paintball"), usually shot from a carbon dioxide or compressed-gas (HPA or N2) powered paintball gun (or marker).
Games can be played either indoors or outdoors and take various forms which are generally divided between woodsball played in natural, wooded terrain and speedball played on open, level fields with artificial obstacles.
Rules for playing paintball vary widely. The most common form involves two opposing teams seeking to capture their opponent's flag and return it to their starting position, but other objectives may include eliminating all of the other team's players or to completing some other objective, such as eliminating a specific player, defending or attacking a particular objective, or capturing objects of interest hidden in the playing area. Depending on the style of paintball played, a game can last from seconds to hours.
