Arma 3 is Bohemia Interactive's military simulation that has defined the milsim genre for over a decade. Set in the near-future Mediterranean, it offers unparalleled combined arms warfare across massive open maps with realistic ballistics, vehicle physics, and squad tactics. The game's longevity comes from its legendary mod support — community mods have created everything from Vietnam War scenarios to zombie survival to Star Wars conversions. While the Enfusion engine successor (Arma Reforger/Arma 4) exists, Arma 3 remains the most content-rich military simulator available, with thousands of workshop mods and an active multiplayer community in 2026.
Arma 3 features distinct areas with increasing difficulty. This guide covers every major location in progression order — what to do, what to get, and when to move on. For the step-by-step path, see our walkthrough.
