The Arma Reforger Experimental is a separate application for both Steam and Xbox. It maintains a build of experimental content and features for owners of Arma Reforger.

Ahead of the main application updates, we prepare the build on this separate public application for testing. This testing period may vary, but the goals are as follows:

  • To allow frequent and flexible updates to test our work publicly.

  • To discover potential issues in the varied player base and receive early feedback. This is complementary to our in-house testing by the various QA teams.

  • To validate ideas, try out concepts, experiment with technologies or content, and gather player feedback on it all.

  • To allow mod teams and other custom content creators to prepare for changes and adapt their works if necessary.

As with Steam, you might have noticed the change in its name, in contrast to the original Release Candidate proposal. However, we believe this terminology helps everyone to better understand its purpose and intended goals for the title. Another benefit of two separate Steam applications, there's no need to switch between branches that would normally involve re-downloading data. Its primary purpose is to allow users an advanced look at features in which to test. Your feedback is vastly important to these builds, and as always, we appreciate your assistance!

Reminder, since Experimental is now released on both Steam and Xbox, crossplay is now available.


  • The Experimental build may still contain issues that we look to address during the testing period.

  • Features and content are still considered provisional and are not guaranteed to be added or adjusted for the main release build.

  • Multiplayer is only compatible with other users of experimental. However, we cannot guarantee what experience or issues players may face while using it.

  • Mods or other custom content may not be compatible with experimental.

  • Frequent updates may occur until the full release, so consider your bandwidth.

  • This build is not 100% representative of a final main release build.
