Halo CE in the browser — “Halo CE · Web”

Our first check found only an opening screen. On recheck, the destination behind it identifies itself: “Halo CE · Web”, a WebAssembly build assembled from open-source decompilation work, with clear copyright handling and surprising multiplayer ambitions.

Source / setup review

You bring the disc image; the host brings the engine.

The project states it “does not provide Halo game data” and asks for an XISO made from your own Xbox copy of Halo: Combat Evolved. That is a legal boundary, drawn in writing, before anything loads.

What the page documents

The buildThe loader credits decompilation projects (halo-ce-universal) and runs the result in the browser. The opening page hands off to the game automatically.
Own-data requirementYou choose an XISO built from your own Xbox disc. The page points to the OpenCE community for disc-ripping instructions and notes it stores only your maps folder locally.
Peer-to-peer lobbiesMultiplayer works through private invite rooms: pick a name and armor color, choose a map (Battle Creek and Blood Gulch are listed) and a mode (Slayer, CTF), then share the invite link.

Prepare your first session

Start from a disc you ownThe only defensible source of the XISO is your own Xbox copy. The project links disc-ripping instructions; follow those, not third-party download offers.
Learn the input mapThe page lists keyboard, mouse and controller bindings, and uses click-to-focus for mouse capture. Check the release control before a long session.
Treat saves as localProgress lives in your browser’s storage for that site. Clearing site data removes it — check before any cleanup.

How this differs from the mobile spin-off

The source list also contains Halo CE Mobile, a separate project with its own file requirements. The two are frequently confused: this one is the decompilation-based desktop-style port with invite lobbies; the other targets phones. Compare both setup screens before choosing.

Has Radiant Guide tested the gameplay?

No. We verified the project identity, the own-data requirement and the lobby documentation on October 13, 2026. We supplied no disc image, so campaign play, multiplayer stability and performance remain untested.
