ACE3 - A collaborative merger between AGM, CSE, and ACE

Recommended Posts



Today we are excited to present to the Arma community the first release of 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.
