Pumpkin Studios made the Warzone 2100 strategy game from 1999 available under the GNU GPL in 2004. A small but very active community of free software enthusiast have been maintaining and improving it ever since. Warzone 2100 3.3, released in September 2019, brought high resolution monitor support, better graphics, smarter AIs and many multi-player improvements. Warzone 2100 4.0 is an even bigger release.
Warzone 2100 has a massively improved graphics engine with support for Vulkan, OpenGL and OpenGL ES 3.0, DirectX (via libANGLE library translating OpenGL ES to DirectX) and Metal (via the MoltenVK library translating Vulkan to Metal). Previous versions were only capable of OpenGL graphics output.
All new high resolution textures to go along with the new and improved graphics engine. The improvements makes this old game from 1999 look like a pretty modern game on a 4K monitor though high resolution monitors will need to use the built-in up-scaling. 200% (4x 1080p) is a good choice for 4K. The game can do up-scaling to up to 400%.
The multi-player mode has a new "Factions" mode in additional to the "Teams" and "Locked teams" modes previous versions had. The multi-player can be used to play against human opponents via the Internet as well as a number of AI bots with different tactics and strategies.
Warzone 2100 4.0 has a brand new soundtrack by LupusMechanicus. There's also a new music manager where you can listen to individual tracks and select what songs should be played in what parts of the game.
The Warzone 2100 homepage is at wz2100.net. It has been overhauled with a slick new look for the the big 4.0 release. A bog button is prominently featured on the front page. It offers binary downloads for Windows, macOS and Debian as well as a Snap installer for other GNU/Linux distributions. The
snap package manager is available for just about all GNU/Linux distributions. Just look for a package called
snap in your distributions package manager if you do not have it installed.
You can install Warzone 2100 4.0 using snap with
snap install warzone2100
and run it with
snap run warzone2100 (it will show up in your desktops menu) once it is installed.
Warzone 2100 is a pretty decent war strategy game. It is worth a look if you have time to play games. This new release really is a big improvement over previous versions, so you may want to take a look if you have played earlier version of it in the past.
