One of PC gaming’s most uncompromising WWII tactics series is getting a full overhaul. Theatre of War: Rearmed launches on PC via Steam on 9 December 2026, bringing every game and expansion in the series together on the latest version of its engine. Fulqrum Publishing announced the date alongside a Steam Next Fest demo in October.
If you never played the originals, Theatre of War sat in the same corner of PC gaming as Combat Mission and Close Combat: real-time tactical battles where armour thickness, shell types and line of sight decided fights, not hit points. It was brilliant, brutal and notoriously hard to get into. Rearmed is an attempt to keep the first two qualities and fix the third.
What’s in the collection
| Game | Original release | Included expansions |
|---|---|---|
| Theatre of War | 2006 | LEHR, Liberation Belarus |
| Theatre of War 2: Africa 1943 | 2009 | Centauro |
| Theatre of War 2: Kursk 1943 | 2009 | Battle for Caen |
| Theatre of War 3: Korea | 2012 | None |
That adds up to more than 100 missions across North Africa, the Eastern Front, Normandy and the Korean War, all running on a single unified engine rather than as separate legacy installs.
What’s been reworked
The series was always known for realism, and equally for being hard to run and hard to read. Fulqrum’s feature list tackles both sides:
- 64-bit engine with major stability and performance improvements on modern hardware.
- Improved visuals and effects.
- A redesigned interface with full high-resolution support, plus refined controls and camera behaviour.
- Reworked ballistics. According to the developer’s Steam update, the calculations for effective armour thickness, ricochets and damage have been rebuilt, with armour-piercing, sub-calibre and other shell types now simulated against historical firing-test records.
- Smarter units. Pathfinding has been improved, wheeled vehicles can now make multi-point turns, and infantry squads’ equipment and characteristics have been reworked.
- Expanded systems for engineering, towing, visibility and interaction, so tanks can repair, transport and support one another more flexibly.
For a series where a bad pathfinding decision could lose you a Tiger tank, those last two points matter as much as the new UI.
Multiplayer and modding
The community tools that kept the series alive are all still there. Rearmed has a large multiplayer component with maps for up to eight players, a mission generator for replayability, and full modding support with a built-in mission and map editor and open resources, so players can create and share their own scenarios.
Demo and system requirements
A free demo ran during Steam Next Fest until 26 October. Fulqrum’s press release described it as nine missions, two battles and a couple of multiplayer maps; the developer’s own Next Fest announcement mentioned 11 single-player missions and three multiplayer maps. Either way, it was a generous slice, and the store page’s listed minimum hardware is modest: a 64-bit Windows 10 system with an Intel Core 2 Duo or AMD Phenom II-class processor.
Who it’s for
Rearmed isn’t trying to turn Theatre of War into Company of Heroes. If you want fast, cinematic RTS action, this isn’t it. But if you’ve ever bounced off the originals because of their interface or stability, or you’re a Combat Mission player looking for a real-time alternative, a complete, modernised collection is the best way in the series has ever had.
The full collection is out on PC on 9 December. For more PC news, see our PC coverage.
