About

OpenAllies recreates Axis & Allies (2004), the real-time strategy game by TimeGate Studios, in Rust with the Bevy engine. The goal is a game so close to the original that a player can barely tell the difference. Menus, HUD, maps, models, animations and texts are read from your own installed copy of the original game.

OpenAllies is a work in progress: a playable test build. There is no download yet. You can follow it and build it from source on GitHub.

What you can do today

  • Custom battles

    Against the computer, on the original setup screen.

  • Campaign and World War II

    Campaign missions and the strategic game, partly: the strategic map, buying armies, fighting battles and returning to the map, saves.

  • Films

    Watch films recorded by the original game, and record your own in the original's format. The original game can open them.

  • Multiplayer

    Between copies of OpenAllies: a LAN game list, Join Direct by address or host name, or online through Epic Online Services. Tested between two copies on one PC so far.

  • All 80 original maps

    Every original map loads.

  • Random maps

    The generator matches the original's world on all 12 maps compared.

Still missing: the editor and saved battles, and most recorded games do not yet replay exactly as they happened.

Status as of 5 November 2026 (Development 24).

  • A mortar regiment walks past red-roofed houses towards a town square with a fountain in OpenAllies.

How close is it?

The original game records every battle as a film of orders. A film plays back correctly only if every result comes out the same, so replaying the original's films is the hardest test there is.

As of 5 November 2026 (Development 24)

  • 12 / 12

    Random maps equal the original's world: every object, both height layers, tiles and the final random state.

  • 52 / 62

    Real recorded films open. The other 10 refuse with the original's own messages.

  • 140 / 266

    Checkpoints match in order on a 2-against-2 Berlin film, about 53 %, up from 32 at the start of November.

  • At least 6

    Real films replay with no mismatch.

  • All

    Checkpoints match when OpenAllies replays its own films: 204 of 204 and 240 of 240 in the runs checked.

Next: the remaining movement differences, then the computer's orders and exact fights.

150 real regiments take about 5 ms a tick, and 2,000 moving men 23 to 45 ms, against the game's 62.5 ms tick.

How it is built

Each system is written from the original game's code and data, then checked against the running original.

  1. Read the original

    Each system is studied from the original game's code and translated exactly into Rust.

  2. Run on the ports

    The game moves onto those exact ports one system at a time and stays playable at every step.

  3. Use the original look

    Menus and HUD are built from the original layout files. Models, animations and textures are the original files from your copy.

  4. Compare with the original

    Behaviour is checked against the running original game: screenshots, unit speeds, damage, recruit times, AI timelines, and recorded films.

  • Faithful

    The same rules, numbers and behaviour as the original.

  • 64-bit

    No 32-bit memory ceiling.

  • No engine limits

    Fixed-size engine arrays become growable. Gameplay rules keep their original defaults.

  • Every platform

    Windows x64 today. Windows on ARM, macOS and Linux are planned.

Build from source

There is no public download yet. The source code is on GitHub under the Mozilla Public License 2.0.

Build from source 
git clone https://github.com/haskbasirat/OpenAllies.git
cd OpenAllies
cargo build --release --manifest-path crates/aa-bevy/Cargo.toml

The game also reads a local folder prepared from your installed game. A single setup tool for that is still to come, so running from a fresh clone needs that preparation first. Online play through Epic Online Services is an optional build feature: it needs Epic's SDK and the project's online settings, which are not in this repository.

Contribute

Contributions follow the original game's code and data. These rules come from the README.

  1. Find the original behaviour in the game's code and data, and cite where in the original it comes from.
  2. Follow the original's steps, rules and order. Take every number from the original data.
  3. Never add features or interface elements the original does not have.
  4. List what still has to be compared with the running original.
  5. Never commit files taken from the original game.
  6. Agree to the Contributor Agreement (opens GitHub): the project's owner owns accepted contributions and can relicense them.

FAQ

Can I download OpenAllies?

Not as a ready-made game yet. You can build it from the source code on GitHub. A setup tool that prepares the game data from your installation is still to come.

Do I need the original game?

Yes. OpenAllies uses the art, sound, maps and data of Axis & Allies (2004) from your own legally obtained copy. Neither this site nor the GitHub repository includes any original game files.

Is it free?

Yes. OpenAllies is a non-commercial fan project and open source under the Mozilla Public License 2.0. You only need your own copy of the 2004 game.

How does online play work?

OpenAllies has a LAN game list, Join Direct by address or host name, and online play through Epic Online Services as an optional build feature. It has been tested between two copies on one PC, not yet between two PCs. OpenAllies plays with other copies of OpenAllies, not with the original game.

Which Windows versions?

Windows 10 or 11, 64-bit (x64), with a Vulkan or DirectX 12 graphics driver. Windows on ARM, macOS and Linux are planned for the finished game.

How do updates work?

Pull the latest code from GitHub and build again.
