Arma: Cold War Assault - Remastered - Community Edition

based on https://github.com/bohemiainteractive/CWR

This community repository continues the official engine and game source code (codename Poseidon) behind Arma: Cold War Assault — the game first released in 2001 as Operation Flashpoint: Cold War Crisis. That release launched Bohemia Interactive and began the technology lineage that later grew into Real Virtuality, Arma, and Enfusion. The code has been modernized to C++20, built with CMake and Clang, with cross-platform support for Windows x64 and Linux x64. Bohemia Interactive released it to the community that has kept this game alive for more than two decades — to study it, build on it, fix it, and create from it. Three things are worth keeping separate:

Source code (this repository)

The engine and game executables, licensed under GPL-3.0-or-later with additional terms under Section 7. You may use, study, modify, and redistribute it, provided it stays GPL and you follow those terms.

The name and brand

"ARMA", "Operation Flashpoint", and the logos are not granted. The trademarks stay with their owners ("ARMA" is Bohemia Interactive's). A fork must be renamed and must not present itself as "Arma" or as an official Bohemia Interactive product.

Game data (separate)

Models, textures, sounds, missions, and voices. These are not in this repository and are not GPL; they ship separately under the APL-SA license. A free Demo is available on Steam.

In short: the code is free software, the name is not, and the game data comes separately. This license covers the source code only and grants no rights to the trademarks.

Quick Start

Development Builds

The quickest way to get the game or server executables is to download the CI builds: https://ofpisnotdead-com.github.io/CWR-CE-builds/

Build Requirements

• Clang
• CMake
• Ninja
• vcpkg

On Windows, run winget install Kitware.CMake LLVM.LLVM Ninja-build.Ninja and follow the instructions for setting up vcpkg to get the required software.

Compiling

cmake --preset win-x64-clang-rwdi
cmake --build build/win-x64-clang-rwdi

On GNU/Linux, use the matching linux-x64-clang-rwdi preset.

Testing

Copy game binaries from dist/ into Steam Demo folder and start.

Layout

• Apps - executable targets
• Engine - engine libraries and Rust Trident tooling
• Master server tools - Rust service and CLI crates
• Tests - test source trees; CI currently compiles them only
• cmake/ - presets, toolchains, vcpkg triplets, and overlay ports
• docker/ - container support for service and runtime environments
• packages/ - ignored local game data staging area
• resources/ - application icon resources
• thirdparty/ - vendored third-party headers and sources

The thirdparty/ directory is excluded from the project's GPL license: it contains vendored third-party code (glad, the RenderDoc API header) under their own respective licenses — see thirdparty/README.md. Dependencies pulled in via vcpkg (vcpkg.json) likewise remain under their own licenses.

Game data / assets — Arma Public License Share Alike (APL-SA)

Game data and assets (models, textures, sounds, missions, etc.) are not part of this repository and are not covered by the GPL. They are released separately by Bohemia Interactive under the Arma Public License Share Alike (APL-SA):

• APL-SA license text: https://www.bohemia.net/community/licenses/arma-public-license-share-alike

Getting game data to run what you build

The compiled binaries need game data to run. You can obtain the free Demo game data on Steam:

• Arma: Cold War Assault Remastered Demo on Steam: https://store.steampowered.com/app/4819000

The full game data ships with the retail game. Whatever you do with assets is governed by the APL-SA linked above; whatever you do with this source is governed by the GPL with additional terms per Section 7 in LICENSE.

Contributing

This is the community continuation of the official source release. Pull requests, bug reports, ports, tooling improvements, documentation updates, and development ideas are welcome here.

Please use issues for bugs and proposals, and open pull requests for source, build, test, or documentation changes. See CONTRIBUTING.md for contribution guidelines.
