Advanced Combat Environment 3 (ACE3)

ACE3 is the collaborative efforts of the former AGM and CSE teams, along with many of the developers from Arma 2's ACE2 project.

This mod is entirely open-source (we are hosted on GitHub[]), and everyone is free to propose changes or maintain their own, customized version as long as they make their changes open to the public in accordance with the GNU General Public License.

ACE3 is built modularly, thus a team can maintain its own tailored version, excluding a select number of components that they don't like, or which conflict with other addons. Larger components themselves, like the medical system and other core features also include various customization options, allowing mission designers and communities to tweak the overall experience.

@Chaplain Kharos, @Vandeiken aka PawelKPL. People who can read have a clear advantage over people that can't.
Instead of the official wiki you could've also just read: The changelog, The couple twitter posts by ACE team telling everyone about it, Any of the issue reports on ACE Github from people that also couldn't read....

@Chaplain Kharos , After a few hours of testing, googling , finally I found the solution, It looks like ace_server.pbo is not needed anymore and ace server side settings are integarted into cba settings. Why it is not clearly written in readme text IDK. What you need is just "cba_settings.sqf" file in the "ARMA3\userconfig" folder. Just copy your ace settings from serverconfig.hpp file and paste it to newly created "cba_settings.sqf" file. It wokrs for me and I hope it will work for you. Just check your server rpt file, you should have line like this:

[CBA] (settings) INFO: Userconfig: File [userconfig\cba_settings.sqf] loaded successfully.

Me and a friend get mismatches for ace despite both of us using this workshop file. Anyone know what might be the cause? So far the only fix has been replacing the whole mod filder content with the github version.
