Arma 3 is a war you can walk into from any angle, and that is both its promise and its problem.
Bohemia Interactive’s military simulation sandbox shipped for Microsoft Windows on September 12, 2013, then reached macOS and Linux on August 31, 2015. It is the third main entry in the Arma series and the eighth installment overall. It is a shooter, a simulator, a strategy game and a tactical exercise at once, played in first person, third person, or from a bird’s-eye view. It is also, 13 years on, still one of the strangest things you can install on a PC.
The pitch is simple. Arma 3 sends you to war. The execution is anything but.

Altis and Stratis in 2035
Arma 3 takes place in the mid-2030s, on the fictional islands of Altis and Stratis in the South Mediterranean Sea. The main plot unfolds in 2034 and 2035, during a multipolar stretch of global instability that follows Western isolationism, economic crises and climate change. The central event is the 2035 “Altis Incident,” a war fought across those islands between the United States-led NATO and the Iran- and China-led Canton Protocol Strategic Alliance Treaty, or CSAT.
The game does not hand you one soldier’s story. Its plot moves through multiple episodic single-player and co-op campaigns, most of them told from different perspectives around that same conflict. Other events reach as early as 2026 and as late as 2039, in places like the Horizon Islands Republic, Livonia, Argana and Malden — the last returning from Operation Flashpoint: Cold War Crisis.
That structure is ambitious. It is also loose in a way that matters. You are rarely one person for long, and the game rarely asks you to care about any of them.
The factions on the board
The two primary factions are NATO and CSAT. CSAT is based on the Shanghai Cooperation Organisation, and the game treats the two blocs as genuine peers rather than heroes and villains. Around them sit a crowd of others, sorted by the game into three forces: BLUFOR, for NATO and its allies; REDFOR, for CSAT and its allies; and INDFOR, for factions not officially on either side.
The named factions include:
- The Altis Armed Forces, the military of Altis and Stratis, ruling the country under a junta
- The Freedom and Independence Army, a loyalist rebel militia led by the Altian government-in-exile
- The Combat Technology Research Group, NATO’s classified black operations special forces unit
- Viper Team, CSAT’s high-tech People’s Liberation Army special forces, the CTRG’s equivalent
- The International Development and Aid Project, a humanitarian aid non-governmental organization
- The Livonian Defense Force, Livonia’s NATO-equipped military
- The Gendarmerie, the Horizon Islands’ gendarmerie and defense force
- Syndikat, a Tanoan criminal organization that later reforms into L’Ensemble, ostensibly an anti-imperialist insurgency but practically no different from its predecessor
- Russian Spetsnaz, special forces units of the Russian Armed Forces
That is a lot of furniture. It is also the point. Arma 3 wants a world, not a set.
Ballistics, recoil and a customizable HUD
The shooting is where the game earns its reputation. Arma 3 is a realistic tactical shooter with accurate and deadly weapons, heavily affected by external ballistics and recoil. You do not spray. You range, you lead, you account for drop. The series has always done this; Arma 3 does it with more refinements and customization, including a refreshed HUD.
Most of the experience bends to the difficulty level you set, and that level can be freely customized. Player guidance assists like map markers and enemy outlines, NPC behaviors like radio callouts and firing accuracy, and HUD elements like crosshairs and player information all shift depending on what you choose. Want a clean screen and enemies who shoot straight? You can have it. Want outlines and forgiving AI? That is on the menu too.
Infantry is the focus, but vehicles are essential and frequently expanded on in the game’s DLCs. The list runs from combat vehicles and armored fighting vehicles to military helicopters, multirole combat aircraft, motorboats and civilian passenger vehicles. Arma 3 also introduces diving to the series, with diving equipment and an underwater firearm built for frogman operations.
Missions range from infiltration and reconnaissance to commanding combined arms operations. Most have specific objectives, but you are usually encouraged to pick your own route to them — silently eliminating targets as a lone marksman, or pushing a multirole squad into battle from multiple flanks. Sometimes you get uncrewed vehicles, artillery and mortar fire support.
The editor is the real game
The feature that outlasted everything else is the editor. Arma 3 ships with a powerful toolset that lets players build their own scenarios, campaigns and mapmodes for both single- and multiplayer use. That is not a side mode. It is the reason the game still has a pulse.
The maps themselves are expansive, officially called “terrains,” with photorealistic land and water environments covering hundreds of square kilometers. Altis and Stratis anchor the base game. The expansions move outward to the South Pacific archipelago of Tanoa, the Strait of Gibraltar island of Malden, the Eastern European country of Livonia, the Western Saharan country of Argana, and several real-life locations including parts of Mainland Southeast Asia and Europe.
From science fiction spin-off to grounded entry
Bohemia’s own history with this game is part of the story. Arma 3 was conceived around 2010 as a science fiction spin-off of the Arma series, then gradually became a grounded mainline entry. Development was stymied in 2012 when two developers were arrested in Greece on charges of espionage for allegedly photographing military installations. The source material does not record how those charges were resolved, and this review will not guess.
Where the simulation fights itself
Here is the tension at the center of Arma 3. It is a simulation first and a game second, and those two goals do not always agree.
The sandbox is enormous. The tools are genuine. The terrain is convincing. But the campaigns that carry the plot are the weakest argument the game makes for itself. Episodic structure, rotating perspectives, a war told from everywhere and nowhere — it produces scale without much attachment. You remember the firefights. You do not remember the people.
The customization cuts both ways too. Letting players tune AI accuracy and HUD clutter is generous. It also means the game never quite commits to how it should be played. A shooter that asks you to set your own terms is a shooter that has declined to make a case.
None of that undoes what works. The ballistics and recoil model rewards patience and punishes bravado, and the vehicle roster turns a firefight into a combined arms problem. Diving was a genuine addition rather than a gimmick. And the editor has done more for Arma 3’s longevity than any campaign Bohemia shipped.
What 7.3 out of 10 means here
The published critical score for Arma 3 sits at 7.3 out of 10, drawn from an IGDB critic aggregate across five outlets. That number is honest, and it is where this review lands too.
A 7.3 is not a knock. It reflects a game that is exceptional at one thing and ordinary at another. As a military simulation sandbox, Arma 3 has few rivals across Linux, PC and Mac. As a piece of storytelling, it is a pile of scenarios wearing a plot. The Altis Incident gives the fighting a frame, but the frame is not why anyone stays.
What matters is the editor, the terrains and the physics of a bullet. Those are the parts that turned a 2013 release into something people still build on. The campaigns are noise. The sandbox is the signal.
7.3 of 10.
