Using the previous version of 1.87 may work, however I cannot guarantee it. YOU WILL NOT BE ABLE TO COMPLETE ALL MISSIONS ON 1.86 DUE TO THE CHANGES BETWEEN THE TWO VERSIONS.Īs there has been a new version of 1.87 that was released in early January 2018, I recommend you use that version to play this campaign. PLEASE NOTE: THIS CAMPAIGN WILL ONLY WORK WITH ROTR 1.87, NOT 1.86.
