Best World War 2 Strategy Games on Steam

World War 2 is the most-simulated conflict in gaming, and the strategy genre is where it gets taken most seriously. The games below cover very different scales - one asks you to run the industry and diplomacy of an entire nation for six years, another asks you to get one squad of riflemen across one field without losing them. What they share is that the history is load-bearing rather than decorative: supply lines, terrain and doctrine decide the fights, not hit points. For achievement hunters this is also one of the deepest genres on Steam, because grand-strategy lists in particular run to hundreds of entries built around specific historical what-ifs.

1

Hearts of Iron IV

The whole war at the national level - production, research, diplomacy and fronts drawn by battle plans rather than individual units. Its 293 achievements are essentially a list of historical what-ifs, which makes it one of the longest and most interesting completion projects on Steam.

Company of Heroes 2

Squad-based real-time tactics where cover, suppression and vehicle facing matter more than unit counts. The achievement list is enormous at over 450 entries and covers campaign, theatre of war missions and multiplayer commanders.

3

Call to Arms - Gates of Hell: Ostfront

The most detailed Eastern Front tactics game on Steam, with direct control of individual soldiers and vehicles down to the ammunition type in each shell rack. Over 400 achievements, many tied to specific vehicles and missions.

4

Steel Division 2

Operational-scale 1944 Eastern Front combat with deck-building and very long sight lines. The pause-and-plan Army General layer sits on top of real-time battles, so it reads as a wargame rather than an RTS.

5

Panzer Corps 2

Hex-and-counter wargaming in the Panzer General tradition, brought forward with 3D units and a long chain of linked campaigns. Straightforward to learn and very deep to master, with 130 achievements across its scenario sets.

6

Men of War II

Direct-control tactics where you can take manual command of a single tank and aim it yourself. The achievement list is one of the biggest here at over 300, spread across campaigns, skirmish and multiplayer.

7

Company of Heroes 3

Moves the series to Italy and North Africa and adds a turn-based campaign map above the real-time battles. A shorter achievement list than its predecessor, which makes it the friendlier entry point of the two.

8

Order of Battle: World War II

Free to start, with theatre campaigns sold separately. Hex-based, specialisation-driven and built around keeping veteran units alive across a whole campaign rather than spending them.

9

Unity of Command II

The cleanest operational wargame on this list: supply is the entire puzzle, and a beautifully presented one. Only 10 achievements, so it is also the fastest completion here by a wide margin.
