Paintballs and airsoft ammo whiz through the air across East Coast Extreme Inc.'s 8 acres of simulated battlegrounds. On wooded fields, forest canopies cast shadows over paintball players as they weave through tree trunks, duck into ditches, and launch more acrylic salvos than a frustrated cartoonist. Elsewhere, splatterless ammo fires across 2 acres of airsoft fields. East Coast Extreme Inc.'s pro shop helps players stock up for these friendly battles. Its rich blue walls enclose a sea of airsoft and paintball gear, including guns with flashlights and laser scopes as well as safety gear.
