T-Square?s 40-acre playing area is a menacing wooded battlefield containing military-style tanks, obstacles, and foxholes from which to taunt, shoot, and telepathically tickle opponents. This Groupon takes care of the field fee ($10), which includes unlimited CO2, 100 paintballs, referees to ensure fair play, and all-day field access. The rental of a high-quality semi-automatic paintball gun and a face mask is also included ($5). For trigger-happy targeters, T-Square offers additional rounds of paintballs for purchase?increase your inventory with 100 ($5), 500 ($20), or 2,000 ($60) paintballs. Beginners and advanced sharpshooters alike will take to the field for rousing games of ?attack and defend,? ?arena ball,? ?capture the flag,? and its not-so-popular offshoot, ?let?s all talk this out before making any rash decisions.? There is an elevated viewing area for non-players to watch the games and shout out defensive strategies in Morse code.
