Sgt. Splatters suffers from some serious problems. Like the other reviews have stated, the worst thing about it is the lighting conditions. They only have a few windows in the huge, warehouse-like field, and in the daytime, the lighting is so poor that I'd rather take the chance of playing outlaw paintball in the local woods. Don't even bother trying to go after sunset, because you aren't going to see your opponent to shoot them.
It also suffers from poor equipment. They use Winchester Durangos (or Sedonas, not sure), which is only marginally better than Brass Eagles. The masks are dirty and disgusting, they are absolutely not sanitized regularly.
The staff does not seem overly helpful as well. Many of them are rude, and unless you shout at them, they won't lift a finger to help you with anything even if you're standing at the counter waiting.
Overall, the atmosphere is not as friendly as I would like. The majority of players are either testosterone pumped, cocky twenty-somethings or adolescent Junior High kids. Neither group are particularly appealing as squadmates, at least as a whole.
I haven't been to other fields, like the Badlands, because I'm not yet 18. But when I finally get there, I'm probably not going to bother with Splatters much. Its cons just outweigh its pros.
