Arma 3: Zeus

Arma 3: Zeus is a free DLC released in 2014 that fundamentally alters multiplayer sessions by introducing a Game Master role. Requiring the base game, this content allows one player to act as "Zeus," dynamically controlling the battlefield by deploying units, changing objectives, and influencing the environment in real-time, similar to tabletop role-playing systems. The core gameplay loop shifts to improvisation for all participants, as the Zeus player crafts a unique, reactive scenario for the standard combatants.
