North Texas Xtreme Gaming's trailer is anything but inconspicuous when it rolls onto a driveway, as it is plastered on all sides with iconic video-game characters. The mobile gaming platform fields five widescreen televisions inside and two more outside, allowing up to 28 players to test their digital mettle. Wii U, Xbox 360, and PlayStation 3 hardware power the action with a full library of games, including popular picks from such series as Super Smash Bros., Halo, and Call of Duty. Guests play in comfort, as the trailer's equipped with heating and cooling systems and stadium seating, and a coach is on hand to offer up game hints or plumbing tips picked up from Mario.
