I went once years ago and I don't think I've ever had a worse airsoft experience. Here's why
Rediculous amounts of cheating done in front of marshalls who did nothing. For example one game had a single respawn fir both teams and a click divided into coloured sections. If the minute hand was in your teams colour you can go back into the game. One player (with a Marshall watching) moved the hand to put it in his teams colour and the Marshall did nothing.
Marshalls more interested in the supposed status of being staff than doing the job.
Rules made to give their regulars a massive advantage
Rules changed I'd game whenever the regulars started to get beaten
Stupidly long wait between games. Anything up to half an hour
Lastly the owner is a cunt who'll be your best mate to your face but start slagging you off behind your back. He's also a thieving shit who'll take money for guns he doesn't have, just search any social media for special airsoft supplies to read up on the bullshit this guy has pulled
