Warzone 2100

Warzone 2100 is a 3‑D real‑time strategy game that places the player in a post‑nuclear world where the remnants of humanity must rebuild and fight for resources. Players command units of “The Project,” constructing bases, gathering materials, researching technologies, and seizing territory against AI or human opponents. The game includes a single‑player campaign, LAN and Internet multiplayer supporting up to ten players, and a unit designer that lets users create custom combat units.

The title is fully open source under GPLv2+ and is distributed for Windows, macOS, and Linux, with installers and packages such as MSIX, DEB, Flatpak, and Snap. Its development is community‑driven, offering access to the source code, development builds, and tools like the Warzone Model Import Tool.

Distinctive features include an extensive tech tree, AI bots, and a focus on replayability through varied strategies and unit customization. The project emphasizes openness, free‑as‑in‑freedom licensing, and cross‑platform availability.
