Counter-Strike: Condition Zero

Counter-Strike: Condition Zero launched on March 1, 2004 as a complete, standalone product containing a full single-player Tour of Duty campaign, over 12 bonus missions, and the classic Counter-Strike multiplayer experience. The store description presents it as a finished, self-contained offering with no mention of future content or ongoing development plans. Post-launch, Valve has issued periodic maintenance updates over the years — most notably a 2013 update that brought Linux and macOS support and migrated the game to the SteamPipe content system, and a November/December 2023 burst of patches that updated the game to support the Half-Life 25th Anniversary engine improvements. These updates are purely technical maintenance: bug fixes, crash fixes, and platform compatibility work. None of them introduce new gameplay content, and none are accompanied by any statement about future content additions. There are no unreleased DLC items, no roadmap, and no developer statement indicating that new content is planned. The game shipped as a complete product over 20 years ago and has been receiving occasional technical upkeep since then. The most recent update was on December 12, 2023.
