This extension ...

• provides interoperability between the Call of Duty® 2 server and other software components and/or advanced game modifications (so-called "mods"),
• intends to improve the overall game experience and security as the extended software (Call of Duty® 2) is not maintained anymore since more than a decade,
• has its focus on the Linux variant of Call of Duty® 2 Multiplayer and can be used with the original game binary,
• and was implemented for non-profit and educational purposes.

⭐ What's new?

The extension requires the server binary for game version 1.3 to be used as basis and supports all three major game versions (check out the sv_version and proxy dvars), including the ability to let players from all those versions to connect to the same server.

  • Allow to show head icons to both teams (via axis_allies)
  • Excluded clients with wrong password from scoreboard
  • Patched Com_PrintMessage so that strings that begin with a caret are printed properly in console
• 🗒 Improvements in documentation and code
  • Added a crash logger that saves debugging information (locally)
  • Added documentation for all new functions and some where documentation was missing
