Playing paintball could cause serious injuries. It could also be an unpredictable activity and lead to more health risks. More serious injuries or accidents can occur if the players run out of paintballs or if they use old or un-tinted ammunition. Some people have been killed when their opponents used live ammunition without protecting themselves first. Paintball is a game played with the help of projectiles that are shot using compressed air or CO2. People who play paintball games have to wear protective gear such as masks, helmets, and body armor. There is no denying that paintball can be a lot of fun and, in many ways, it's also a great way to spend time with friends.
