Sickboy informed us that he has released the Advanced Combat Environment 2 OA version 1.13 stable on the BI forums. Also the Community Base Addons have been updated to version 0.8.3.175, make sure to update your CBA version!
Quote : ACE Mod is a full conversion modification, focusing on gameplay, realism and authenticity, providing you with an 'Advanced Combat Environment'. With ACE, skills, tactics and teamwork are more important, adding new dimensions to the battlefield.
Thanks to all people involved, enjoy! Especially to all of you who tested it and reported problems to help us to improve ACE even more!
