I caught a glimpe of it in the background, & thought it looked more like airsoft to me! Note that though many of the players were wearing goggle systems, they didn't quite look like any make that I recognised & the guy overseeing them was just wearing Uvex goggles or something similar. Also, the size of the bruises was far too small to have been caused by .68 paintballs! Maybe they were using those little .5 balls they make for use with the kiddies markers (the ones that look lkike supersoakers) or those megasplat electronic powered "executive toy" paintball guns.
