0.3.75 Mac, Windows, Linux testing-75

testing-75. Network protocol 41.

A clip recorded on another build plays through. A clip recorded on this build still stops if the players are not where the recording left them.

A cloaked weapon in your hands is drawn with the ordinary depth test. A nearby wall can cut it. Camouflage on other players is unchanged.

A machine that joins during a co-op cutscene sound starts where the host has reached, through the pitch and permutation that machine picked. A dedicated server waits for the linked parts before it stops the sound, so a long chain is not cut off early. An older client starts at the beginning.

Mac: open OpenCE-macos-arm64.dmg and drag OpenCE into Applications. This build is for Apple Silicon and macOS 26 or later. The app is ad hoc signed. If macOS blocks the first open, allow it in System Settings under Privacy and Security.

Windows: unzip halo-windows-release.zip and run halo.exe.

Linux: unzip halo-linux-release.zip and run halo.

Bring your own copy of the game. The download has no game data.

This is a prerelease. A copy already on testing build 74 offers it the next time it starts. A main build leaves it alone until Testing Releases is turned on.
