Mouse and keyboard support is confirmed for the browser version of Halo: Combat Evolved; controller support and gamepad configuration are not. A related Cybersecurity port documents gamepad input, but its instructions do not establish that the browser build works the same way.
What input does the browser version of Halo support?
PC Gamer reported on October 1, 2026, that the browser rendition has full mouse and keyboard support. Its report does not say whether the game accepts a controller, how to map one, or which browsers and devices might work with a gamepad. The browser project combines a decompilation project with a fork from the Cybersecurity team, but that relationship alone does not confirm that the live browser build shares the fork’s input features.

That means controller compatibility is unconfirmed—not established as either supported or unsupported. Do not assume a controller model, operating system, browser, or remapping menu will work based on the available browser-build reporting.

How to check for controller input without assuming support
If you want to try a controller, treat this as a general troubleshooting path, not verified instructions for a particular Halo browser port:

- If input is not recognized, consult help or controls documentation for that exact build, if available. Do not substitute instructions for another Halo release or port.
No specific browser/device combination or controller configuration steps are established for the browser build in the cited report. A purchase decision based on compatibility should wait until the exact build confirms gamepad support.
What the related Cybersecurity port documents
The Cybersecurity port README describes gamepad input and configuration for its own build. It says keyboard and mouse operate controller 1, the first gamepad’s input is added to controller 1, and other gamepads operate controllers 2 to 4. These details are useful as a comparison, not as proof of browser-port behavior. Cybersecurity port README

- Mouse wheel or 1 changes weapon; Q toggles the flashlight.
- Z or the middle mouse button zooms; Tab opens scores; Escape pauses.
Where that port configures input
In the documented port, keyboard and mouse actions can be changed in Settings > Controls Setup or in the [controls] section of config.toml. Gamepad layout is configured separately at Settings > Gamepads. Those paths describe the related port only; they should not be presented as menus or files available in the browser game.

Why Halo: MCC controller instructions do not apply
Halo’s official update documents controller customization in Halo: The Master Chief Collection (MCC). That is a separate product, so its settings are not evidence of browser-port menus or controller compatibility. Official MCC update
