That video is staged, but it still looks fucking amazing!
I love paintball, and one center in my area has a really nice arena, with an old army med-truck, sand bunkers and camouflage nets on top of trenches. But it's not as big as it sounds, just big enough for 4v4. And there's another center more far away wich is located near a runway, and people used to shoot at the landing planes ^^
