Have been to Fearless Fighters about 5 times and each time there have had the same expirence. They claim to have many fields but we always play on the field closest to the office. The main owner acts like a jerk, except for one time when he wasn't there. They claim to have other fields, where are they? Thunderball is a good concept, bring your own gun and use your own paint. Don't buy their paint, it is about double the price!! The problem with thunderball though is that you play for 10 minutes and then sit for 20 or 25. Just as the game is getting good, they blow the whistle and you have to leave the course. Also if another private group shows, instead of taking them to another field, you have to wait on them and loose thunderball time while they play.
Thunderball is a good idea, a lot of potential at this place, but the bottom line here is not paintball, it is "how much money can I get out of those who come here to play"?
