Near the runways of O'Hare Airport, O'Hare Paintball Park hosts competitors inside its 25,000-square-foot indoor arena. A quiet staging area away from the noise of roaring opponents lets combatants prepare for each skirmish before storming the field with paintball guns in speedball or scenario matches. Red and blue speedball-format obstacles lend cover during quick elimination games, and inflatable hummers, log cabins, and wooden boxes conceal warriors in themed games to give an authentic war-zone feel. Experienced staff members interact with players before and after matches by assisting younger competitors, offering strategies for overcoming difficult situations, and offering techniques for painting Monet's Water Lilies on opponents' bunker walls. O’Hare Paintball Park is open to the public Thursdays through Sundays.
