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.

I unzipped the CBA3.8 and manually updated the mod to Arma3 but the mods wont recognize it it will only recognize 3.6 CBA on the steam workshop.

Issue with ACE. Is it normal for the command bar at the bottom of the screen to vanish? (The one that shows your squad/units).

Have no problems with cba! Both (cba + ace) from workshop! Cba v3.8.0; ace v3.12.3!

When i try to lock on to an enemy the square doesn't pop up. Is that a new feature or a bug?

@Ellman which one are you using I got the official one adn it is not working :SmileCube:

Take the "@ace" folder and place it in your default Arma 3 directory. Usually located in "program files -> steam -> steamapps -> common -> Arma 3.

Correct ACE3 features a realistic medical system.

Make sure you got the correct CBA. (Mine is working fine)
