A still figure stands silently behind a few thin trees. When he sees someone emerging from a long, metal tube several yards away, he takes aim with his marker, squeezes the trigger, and watches a blot of brightly colored paint materialize on his friend's shoulder. Such friend-turned-foe scenarios play out daily at Urban Assault, a paintball facility whose outdoor battlefields in Cecil and indoor arenas in McDonald attract players from all around the area. In the outdoor arenas, the surrounding wooded landscape adds variety of terrain and barricade possibilities, letting staffers add touches such as metal crawl tubes and other strategic bits of architecture that paintballers have come to depend on for cover. The competitors engage in open play on five such outdoor fields—each with unique features—as well as in the company's two indoor spaces that total some 30,000 square feet. Indoors, paintball contests go from sparsely adorned to almost disco-like as players stalk their enemies while traipsing across catwalks and navigating a demanding maze of fog machines, black lights, and adrenaline-boosting music inside one of the fields. The brains behind Urban Assault also offer special rates to large groups, military veterans, and members of the CIA's finger-painting brigade.
