Arma 3 is a military sandbox set across expansive islands and other simulated theaters of war. Its campaigns range from combat on Altis and Stratis to the cooperative Apex Protocol in Tanoa, while First Contact follows an encounter with an alien presence. Alongside those story-led missions, the game offers scenarios, showcases, challenges, and tools for shaping a more open-ended experience.
The defining play is tactical combined-arms warfare: players can take infantry roles, command a squad, drive armored vehicles, or pilot helicopters and jets. Realistic ballistics and careful maneuvering make terrain and teamwork central to engagements. Loadouts can be tailored with weapons, attachments, clothing, and equipment, while operations span air, land, and sea. This breadth lets Arma 3 shift between close infantry action and larger coordinated military scenarios without losing its simulation focus.
Its format also ranges well beyond a fixed campaign. Players can cooperate in official modes such as Combat Patrol and Escape, compete in Warlords, or explore community-created multiplayer modes; Zeus adds a Game Master who can shape other players’ battlefield in real time. The Eden editor and Steam Workshop extend that flexibility through custom scenarios and user-made content.
