Short answer
Warzone 2100, the 1999 3D real-time strategy game, has been free and open source since Eidos released its code in 2004. The community Warzone 2100 Project maintains it for Windows, macOS and Linux and runs an official Web Edition you can play in a browser tab. Nothing to buy, no original files needed. Latest release: 4.7.0, 7 April 2026.
This site is not affiliated with the Warzone 2100 Project, Eidos or Pumpkin Studios. We do not host any files; Play opens the project’s own page in a new tab.
What it is
Pumpkin Studios made Warzone 2100 and Eidos published it in 1999 for Windows and PlayStation. It stood out for fully 3D battlefields, a huge research tree and a unit designer that lets you combine bodies, propulsion and weapons freely.
The README tells the rest: “In 2004, Eidos (in collaboration with Pumpkin Studios) decided to release the source for the game under the terms of the GNU GPL - followed later by the remaining music & video files” (Warzone 2100 README). Since the code was freed on 6 December 2004, the community has replaced every proprietary component with open-source ones and kept improving the game under the name Warzone 2100 Project.
Current status
- Status: Working, actively developed. The repository was last updated on 2 November 2026.
- Latest release: 4.7.0, 7 April 2026, for Windows 7 to 11 (installer, including Arm64), macOS 10.14 or later (universal), Ubuntu 22.04 and 24.04 packages, Flatpak (x86_64 and Arm64), Snap, and a source tarball for Linux, BSD and other systems.
- Web Edition: play.wz2100.net offers the browser version next to the full download. We could not test it ourselves: our test browser lacked WebGL 2, which the Web Edition requires. The project lists Chrome, Firefox, Edge and Safari as supported.
Web Edition or full version?
The official comparison page sets out the differences:
- Videos: the Web Edition streams low-quality campaign videos on demand, so it needs an active internet connection.
- Saves: supported in the browser, but “some browsers may clear this data unexpectedly”.
- Languages: most of the full version’s languages.
- Performance: rated “OK” in the browser.
Online multiplayer, mods, high-quality graphics and music, and the add-on campaigns are reasons to use the full version. For a quick skirmish or to try the campaign, the Web Edition is enough.
What you need
- Nothing to buy. All code and data are freely licensed.
- For the Web Edition: an up-to-date desktop browser with WebAssembly and WebGL 2. If your browser lacks them, the page says so.
- For the full version: a Windows, Mac or Linux computer. The game supports OpenGL, OpenGL ES and Vulkan, so it runs on modest hardware.
How to start
- For the browser, open play.wz2100.net (Play button above) and choose Web Edition: Play Now.
- For the desktop, download 4.7.0 from wz2100.net or the releases page, or install the Flatpak or Snap on Linux.
- On Ubuntu, the README recommends downloading the campaign videos separately (
sequences.wzfrom the project’s wz-sequences releases) so you do not miss story briefings. - Start the campaign, a skirmish against AI bots, or an online game.
What the community version adds
From the README’s highlights:
- A remastered single-player campaign with persistent, expanding bases and away missions.
- Online multiplayer for up to 10 players, free-for-all or teams, cross-platform.
- Local skirmish against AI bots.
- A tech tree of over 400 technologies and the flexible unit designer.
- Multiple graphics backends: OpenGL, OpenGL ES and Vulkan.
- Mods and many languages.
Common problems
- “Unsupported Browser” on the Web Edition: your browser lacks WebAssembly or WebGL 2. Update it, enable hardware acceleration, or use the desktop version.
- Lost browser saves: private windows and some cleanup settings wipe site data. Use the desktop version for a long campaign.
- No campaign videos on Ubuntu packages: download the sequences file as the README describes.
FAQ
Is Warzone 2100 free?
Yes, completely. Eidos released the source code under the GNU GPL in 2004, and the music and videos followed. The community-run Warzone 2100 Project gives the whole game away for Windows, macOS, Linux and the browser. There is nothing to buy and no original disc needed.
Can I play Warzone 2100 in my browser?
Yes. The project runs an official Web Edition at play.wz2100.net for current Chrome, Firefox, Edge and Safari. It needs WebAssembly and WebGL 2. Videos stream in low quality over the internet, and browser saves can be cleared by some browsers, so the full download is better for long campaigns.
Does Warzone 2100 have online multiplayer?
Yes, in the full version. The README lists online games for up to 10 players, free-for-all or teams, with cross-platform play, plus offline skirmish against AI bots.
What is the latest version of Warzone 2100?
On 3 November 2026 the latest release was 4.7.0, published on 7 April 2026, with builds for Windows 7 to 11, macOS 10.14 and later, Ubuntu, Flatpak and Snap.
Is this the same game as the 1999 original?
It is the same game, continued. The community has replaced all proprietary parts with open-source ones and added a remastered campaign, a bigger tech tree, Vulkan graphics and many fixes, while keeping the original's design.
