A Long History

Warzone 2100 was originally developed by Pumpkin Studios and published by Eidos Interactive. In 1999, it was released commercially for Microsoft Windows and Sony PlayStation. Pumpkin Studios ended their support for Warzone 2100 on January 5, 2000.

In 2004, after fan petition, Warzone's source code was released publicly under an open-source license. It has been developed, maintained, and improved by the community ever since, under the banner of the “Warzone 2100 Project”.

Log in with itch.io to leave a comment.

I have two questions:

1. Is there a reason the Linux version isn't on Itch.io ? (I suspect it's because it's in plenty of repos but I figured I'd ask)

2. I see on Github that there is an Arm build but only for Windows, are there any plans to make a Linux Arm build ?
