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.

FIX THE NVG'S! This mod is absolutely beautiful in every possible way, but the NVG's look nowhere near realistic. Using them feels like being stuck in a green blizzard or something, absolutely dreadful. I genuinely hope that the creators of this mod will look into this. Other than that the mod is great. Thank you

Hola soy novato en esto del ACE, mi pregunta es cuando juego solo, como diablos me curo si me hieren ? me acabo desangrando pues a pesar de tener vendas no consigo poder utilizarlas. ALgun tutorial de como usar el medico ? quiero desactivar todo lo referente a el apartado medico porque de momento lo veo demasiado complicado para mi.

hello, I have a question: is it a habit to provide mods that always kidding? seriously, the problems are always the same. that it is with or without file of compatibility. so, will an update be available with ALL missing files? Or do you have to download hundreds of files to make it work? file ace_fcs.pbo, ace_compat_sma3_iansky;ace_compat_rhs_de; _adr_97;_rhs_gref3;_rhs acc;_rksl_pm_ii;_r3f;_rhsafrf3;_rhs_usf3_rhs usf3_sub;
I installed no less than ten compatibility files. The problem is always the same.

@1st Lt. Barnett [F/2/505 PIR] I mean I can run for a while but the stamina will never regenerate. So after that initial run for the rest of the time my soldier is alive he will have a super small stamina so if I move a few meters and try to aim my guy will freak out all tired still. And the heavy breathing lasts forever and never goes away. ):
