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.

ok, i cannot for the life of me get a chinook that we have fully repaired and it is driving me nuts. Is there a way to enable it so with this mod on that when you come up to a repair rearm or refuel container that it automatically does the action rather spending an endless amount of time trying to find the interaction points to repair something?

Wish there was a search for comments.... Running ACE with Warlords and noted on the score screen its not tracking players kills...

Anyone have a workaround for this yet or is it a setting in ACE I am over looking?

Hello guys,
does anyone know if there is a way to lower down the accuracy of the IA or at least modify the IA skill ? , because i love ACE , best mod ever in my opinion , but the IA is too strong and accurate(for me), its sad there is no way to choose wich difficulty you want to have , since with ACE the default IA settings are desactivate. If someone have a solution it will make my day.
