Proving Grounds Paintball entices color warriors ages 10 and older with elaborate battlegrounds to support all manner of splatter-fueled play. Sharpshooters gear up with rental equipment, strapping on ammunition belts, pulling on goggles, and fueling a Tippmann semi-automatic marker with a tank of nitrogen before taking to the fields to reenact the famous frescoing of Bunker Hill. A pair of tanks with moving turrets guard a 50-foot snake on the fast-paced hyperball field, whereas a changing configuration of inflatable bunkers on the two airball fields eliminate any home-field advantage. Feet dash up a high tower on the castle field, gaining a vantage point from which to carefully consider composition and balance before subjugating adversaries swarming over the ramparts and courtyard below.

Hunters hungry from the chase may snack on provisions brought from home or design a complex system of underground tunnels leading straight into the on-site concession stand. Proving Grounds Paintball recommends that patrons bring old clothes to play in, pointing out that long layers are the best option for dulling the sting of a painted pellet or a sneak attack by enemy mosquitoes.
