Classic Offensive Mod Shut Down at Valve's Request
The mod that was supposed to bring back the spirit of classic Counter-Strike 1.6 on the CS:GO engine will never see the light of day. After eight years of intense work and even official approval from Valve, the Classic Offensive development team was forced to completely cease development at Valve's request.
From Greenlight to Ban
The Classic Offensive project began back in 2017 when the developers received official approval from Valve through the Greenlight platform. This gave them access to Steamworks and confidence in a future release. The mod was intended to combine the classic mechanics and visual style of the legendary CS 1.6 with the modern capabilities of CS:GO. Over eight years, the team overcame technical difficulties, adapted to CS:GO updates, and confidently moved toward the final release.
How Valve Changed the Rules of the Game
In October 2024, the final version of the mod was submitted for approval on Steam. However, by January 2025, the developers received an unexpected rejection with the reasoning "does not fit," without further explanation, as we wrote in our article. After this, the team decided to release the game on ModDB, but just hours before the release, they received an official Cease and Desist order from Valve.
Later, company representatives explained that the release of Classic Offensive is considered the distribution of derivative content based on Valve's intellectual property. This allegedly violates the terms of the Steam Subscriber Agreement.
Valve Reassesses Its Relationship with the Modding Community
Now, according to the developers, Valve only allows limited types of user content: skins and maps published in the Workshop, original non-commercial projects on Source SDK 2013 without using the company's IP, as well as modifications for Half-Life 2 and Team Fortress 2 within certain rules. Everything else, including major mods and builds for CS, L4D, PortaL , no longer aligns with the new policy.
This contradicts decades of an open approach to modding, which launched many of Valve's projects, including Counter-Strike itself. The decision effectively deprives the community of traditional creative channels and leaves developers without legal protection even in cases of official approval.
The story of Classic Offensive is not just the cancellation of one project. It is a turning point for the entire modding community. Valve, once inspiring thousands of fans to create new content, now demonstrates an unpredictable and strict stance. Even if a project was approved and met all requirements, the company reserves the right to reconsider its decision at any time.
