I believe the movie opens with someone being chased by kids in the woods dressed in camo. It looks like a paintball match but i think people are killed. I also remember this kid is new in town and there's a scene where either he's a pool boy and this girl is watching him or vice versa. Eventually the two start talking and the girls jealous boyfriend gets pissed. It's not Master Blaster. Gotcha or Paintball. It was out around the time of The Wraith with Charlie Sheen.
