Half-Life in the browser — the Pixelsuft build

The source reply’s Half-Life link leads to pixelsuft.github.io/hl, a setup page for an Xash3D FWGS Emscripten port. Understand what an engine port is before you expect Valve’s campaign to appear.

Source / setup review

An engine setup screen, not a packaged game.

The page identifies the Xash3D FWGS port and shows a “Memory size” setting before launch. We did not reach a running game scene.

What the page documents

The engineXash3D FWGS is the long-maintained open-source reimplementation of the GoldSrc engine, the engine Half-Life runs on. This destination compiles it to WebAssembly so a browser can execute it.
A pre-launch settingThe page exposes a memory-size option. WebAssembly builds allocate a fixed memory pool, so this choice can decide whether a heavy game data set starts at all.
What it does not includeThe page shows no game content of its own. Engine builds of this family are separate from Valve’s game data.

About game data

The page itself does not state which files, if any, it accepts. Public Xash3D documentation describes engine-only builds that expect game data from the player’s own Half-Life installation. Treat that as background context, not as a promise made by this page — confirm the current setup screen before assuming anything about required files.

Prepare your first visit

Read the setup screenNote the memory-size options and any file picker before launching. Screenshot it if you need to compare attempts.
Do not supply files you cannot verifyA copy of Half-Life you actually own is the only defensible source of game data. Files offered by strangers in chats and forums are a malware risk.
Give the build resourcesClose heavy tabs before raising the memory setting; a failed WebAssembly allocation usually looks like a silent freeze.

Has Radiant Guide tested the gameplay?

No. We verified the port identity and the setup screen on October 13, 2026. Whether this build reaches a menu, loads game data or sustains a session is unconfirmed.
