The devs had said many times, the alpha and part of the beta was not going to have protection. Battleeye is being tested on the dev branch. Battleeye has a lot to do because Arma is so open, it has to find who uses acual as apposed to someone with normal community mods.

Any video of cheaters what did you see ?

Hi,
Everyone is well aware that script kiddies exist and BattlEye is still work in progress. There is no point giving them any undue attention, it's what they want.

I'll close this ticket.
