I don't know what rating should I give, there is no way to play this if no one is playing, and the clasification... well, there are guns, so maybe is fine with M but needs blood for it, I don't know, how would I know if I can't play this game?
What I recommend, is to add a single player, I think I understand the game, and I don't know how others can't understand
Maybe online is not working fine, maybe you need to test with someone, or if online is alright them well I don't know, just try to do a single player and maybe more people will get to play this because them they will understand
