- Valve has not published a mobile version of Counter-Strike. The Counter-Strike 2 page on Steam lists Windows and SteamOS + Linux under System Requirements, and Valve's own CS2 page describes the game as a free upgrade to CS:GO.
- Two fan projects account for most of the mobile and remake chatter: Counter-Strike: Mobile Offensive by the indie team TRYMISS, and CS:Legacy by the ProMod team.
- Neither is published or endorsed by Valve. Both are built by independent teams and both are described as fan work.
- Valve has previously taken down fan projects that monetize or use its intellectual property without authorization, so the safest rule is to check the developer on the store page before you download anything.
Valve's Counter-Strike 2 page introduces the game as a free upgrade to CS:GO. The Steam store page for Counter-Strike 2 lists the supported platforms in its System Requirements section, and the list is Windows and SteamOS + Linux. No mobile platform appears there. Valve's news feed is the official channel for releases and updates, and no mobile release has been posted.
That matters because every mobile Counter-Strike project announced so far is fan work, and it is easy to mistake a fan trailer for an official release from a distance.
Counter-Strike: Mobile Offensive
Counter-Strike: Mobile Offensive comes from TRYMISS, a small independent team that describes the project as fan-made. It has been in development for more than a year, and the developers released a trailer on YouTube showing classic maps, touch controls designed for phones, and a build they say comes in under 2 GB. The announced release date is November 26, 2026 for Android and iOS.
The same coverage is explicit about the relationship with Valve: the game is not endorsed or affiliated with Valve. Valve has previously taken down fan projects that attempt to monetize or use its intellectual property without authorization, which is worth knowing before you treat a trailer as an official announcement.
CS:Legacy, the CS 1.6 remake
CS:Legacy is a separate project by the ProMod team. It was revealed through a YouTube trailer and is built from the ground up on Valve's 2013 Source Engine SDK, with major systems such as the renderer and shaders rewritten. Dot Esports describes it as a standalone release rather than a mod, and reports that the developers confirmed a Steam early access launch without a fixed date.
How to tell an official release from a fan project
1. Check the store page. An official Valve release is published by Valve Corporation and appears on Valve's Counter-Strike 2 page and on the Steam app page for app 730.
2. Check Valve's news feed. Valve posts its own releases and updates there, so an absence is information.
3. Read the developer's own description. Fan projects usually say fan-made and state clearly that they are not affiliated with Valve.
4. Treat any Counter-Strike mobile download that is not on the official store page as unofficial.
