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.

Why is ace 3 for A3 so soft and weak compared to the one in A2 to the point it feels arcadey? Without the MSE medical it would be useless and it even interferes with A3's hit detection. Vehicles don't catch on fire, soldiers don't detect heat, there's no suppression or "shock" effect, no fatigue or fainting, no nothing from A2 and the reason why people played ace in 1st place is actually that very reason - that ace provided something vanilla didn't.

When I launch the game with the mod enabled, I get a message saying ace is not compatible with the 64-bit version of the game? I never got this message before. Did something change or is my install just bad?
