About Warzone 2100

Warzone 2100 places you in a post‑nuclear 21st‑century where the NASDA defense system malfunctioned, erasing modern civilization. You join The Project, an organised survivor group that seeks to rebuild using pre‑war technology while confronting hostile scavenger bands.

The game is fully open source and runs on Windows. It offers a single‑player campaign with full FMV support, several skirmish modes, and both online and LAN multiplayer for PvP and co‑op play.

01 / THE GUIDE

Campaign Narrative

The single‑player campaign follows The Project’s survivors as they explore the devastated world. Full‑motion video sequences support the campaign, helping convey the story of the NASDA failure and the group’s rebuilding goals.

Mission objectives advance alongside the story, gradually unlocking new technologies. This progression ties narrative milestones to the expanding toolbox available to the player.

  • Watch FMV intros for hints about upcoming technology themes.
  • Notice how later missions grant access to newer research options.

02 / THE GUIDE

Technology Tree

Warzone 2100 includes an extensive tech tree containing over 400 distinct technologies covering weapons, sensors, radar, and vehicle components. Technologies become available as you progress through the game.

Because the tree is so broad, players can explore many branches, such as artillery upgrades or counter‑battery radar, without being forced into a single path. The sheer number of options distinguishes it from many other RTS titles.

  • Browse the tech tree early to identify branches that match your preferred tactics.
  • Track which technologies unlock new vehicle parts for future designs.

Vehicle Design System

A vehicle design system lets you assemble custom units by selecting chassis, weapons, and sensors from the technologies you have unlocked. Each component contributes specific stats, allowing you to shape a unit’s role.

Design choices directly affect battlefield performance, making vehicle creation a core strategic element. Testing different configurations helps you adapt to evolving enemy tactics and mission requirements.

  • Experiment with designs in skirmish mode before using them in campaign missions.
  • Balance armor and firepower to avoid overly specialized units.

04 / THE GUIDE

Multiplayer Modes

Warzone 2100 supports both online and LAN multiplayer for PvP and co‑op skirmishes. Players connect via the internet or a local network, using the same core mechanics as the single‑player experience.

Online play requires port forwarding; the description advises checking local router settings to enable connections. Both competitive and cooperative matches benefit from coordinated technology choices and vehicle designs.

  • Verify your router’s port‑forwarding settings before attempting online matches.
  • Discuss research priorities with co‑op teammates to avoid duplication.

05 / THE GUIDE

Open Source Availability

The game’s source code is publicly available on GitHub, confirming its fully open‑source status. Community members can view, modify, and redistribute the code under the project’s license.

Access to the code enables players to verify mechanics, contribute bug fixes, or create custom content, extending Warzone 2100’s lifespan beyond its original release.

  • Browse the GitHub repository for community patches or enhancements.
  • Consider contributing documentation if you discover useful insights.
