Every year, more than 20,000 players arrive at Paintball Nation's two locations to playfully trade paint across outdoor battlefields or among towering indoor obstacles. Sniper towers overlook Mississauga's urban scenario field, where misfired paintballs splatter against trucks, tires, and wooden boxes. During summer months, Brampton's outdoor facility hosts paintball squadrons as they launch technicolor salvos amid fresh air and sunlight.

Whether games take place indoors or out, Paintball Nation's referees make sure simulated battles remain safe and good-natured. To that end, they brief every visitor on field rules and etiquette, such as never using non-field paint or unlicensed Blackhawk helicopters.
