Game entry check
Play Half-Life in your browser: what we checked
Two bare browser builds based on the Xash3D engine. Their pages say very little; we could read only a title and a settings field.
What this page is. We fetched the entry page over HTTPS and read its title and visible text. We did not play the game, sign in, or test performance. Radiant Optimizer itself is Windows tuning software and does not provide this game.

Entry pages
| Link | Status | What we saw |
|---|---|---|
| pixelsuft.github.io/hl | Opens | Titled "Pixelsuft hl". Visible text: "Xash3D FWGS Emscripten port" and a memory size setting. |
| x8bitrain.github.io/webXash | Opens | Titled "WebXash". The page renders with scripts, so the visible text is only the title. |
These are third-party sites. We do not operate them and cannot vouch for their content beyond what is listed here.
What we observed
- The first page describes itself as a Xash3D FWGS Emscripten port and shows a memory size setting.
- The second page showed only its title, with no description, publisher or instructions.
What we could not confirm
- We could not tell what game data these builds load or whether you must supply Half-Life files. One directory labels them as needing your own files; we have not verified that.
- The pages give no publisher or licensing information.
- We have not played either build.
Before you click
- Do not install browser extensions, run .exe files, or enter account passwords for a "browser game".
- Browser versions of 3D games usually need WebAssembly and WebGL 2. Check yours on the browser check page.
- School and work devices may block these pages. Follow your network's rules; we do not help bypass filters.
