Paintball is a sport in which players shoot each other with small paint pellets fired from air guns.
Many variations on the game can be played. Players are eliminated from the game when they are hit with a paint pellet. The winning team is the one which has accrued the most points when time runs out. Points are given for elimination's, capture of the other teams flag, and hanging the other teams flag in your own flag area. You don't have to have an organized team or go to an organized field in order to play.
