This is an interesting Paintball Arena that I use on my server. I consider it a snipers paradise.

Also, there's a secret underground cavern... But since my server is small, the map would be too large... So I use invisible Multiverse Portals on to deny access... essentially cutting the map size in half. I also use these invisible multiverse portals in some of my other maps... in case players glitch outside the boundaries of the arena, it'll teleport them back inside.

Lemme know what you guys think about this map.
