The combat controllers of Battlefield Houston supervise their own indoor arena, an 11,000-square-foot, multifloor battleground designed with routes resembling city streets and alleys, and walls resembling burnt-out façades of old stone buildings. Here, players engage in a range of themed games and special scenarios that encourage them to destroy a target to protect another player.

The playful battle cries that drift across the field are fueled by realistic weapons, each hand-built with a realistic heft and designed to sound fire in the style of their real-life counterparts. The arms are equipped with small laser sensors and eliminate the need for additional bulky vests, which has contributed to their use in the training programs of SWAT and law-enforcement teams and military personnel.
