Players duck behind the husks of one-storey huts, towers, and abandoned cars as they navigate a grassy labyrinth. Others dart between industrial concrete walls, firing at the enemy from behind padded barriers. On seven more outdoor fields, teams advance in tandem between towering spruce trees or over hills and valleys, seeking the refuge of wooden fortresses and the coziness of trenches. Whether competing on the Okotoks location's 80,000-square-foot outdoor field, the Calgary location's 28,000-square-foot indoor arena, or Millarville's 55 acres, visitors to Rampage City Paintball immerse themselves in a range of capture-the-flag scenarios. Experienced staff oversees each 15-minute game, and outfits players with Tippmann gear and protective bodysuits. They also supply gear upgrades such as semiautomatic Tippmann guns, goggles, and temporary-invisibility dust.
