Gurdman

Confused on the whole situation of me being forced to beta test through these new patches on arma that have now made it impossible to play anything on arma but day z. I believe the reason is that I purchased the game on steam which forces me to download the latest version of the game, thus making me stuck with the broke version. What I want to know is if I can revert back to 1.60 so I can play on the domination servers on arma. Thanks for the help!
