Open Halo CE is a non-commercial, open-source project based on the Halo 1 decompilation project. Its website provides an interface for playing the game, with access conditional on users confirming that they own a copy of the original title. The experience includes a lobby that displays connection status and a chat area where participants can send messages.

The site also provides a mobile-use prompt asking players to turn their phones sideways before playing. These visible features position Open Halo CE as a community-oriented way to access a play experience built on the project’s underlying decompilation work, rather than as a commercial game seller. The website emphasizes both its open-source, non-commercial status and the ownership requirement, making those terms clear before play.

Its interface is focused on getting users into the game and offering basic lobby communication. No additional products, paid services, development details, or supported platforms are specified in the available site text
