With hacks like Helios and Zillion not any fun at all. Don't waist your time.
The anti cheat the is out there is only begging update for certain groups leaving the game wide open for cheaters.
Unless you have some friends that you trust I would suggest playing this on a LAN game only leave the idiots with no place to play and maybe one day it will be worth playing on line once again.
Over and over again I have heard the idiot admins running the only populated servers out there say no one is cheating in this game and yet again I see it all the time.
Don't waist your time downloading the demo get the retail version and play locally if you play on line you will be very disappointed.
