What we know
An unofficial port by Slqnt and 98006 that runs in a browser tab on WebGL 2 and WebAssembly. Coverage says the main campaign and both episodes work. One report notes it remains at the mercy of a quick DMCA takedown. Update: when we checked on 2026-10-08, hl2.slqnt.dev returned a 404 error, so it may have been removed.
