One program you keep
NoireMultiplayer.exe brings your game folder up to the current release, shows who is playing where, and starts the game on the server you pick. It updates itself, so this is the only address you will ever need.
Testers only, for now
The launcher is how testers get the build — it replaced the zip packs — but this is not open to everyone yet. Servers are run by and for the tester group while vehicles and combat are still being fixed. Ask in the Discord: run /apply, answer four short questions, and accepted testers get the Tester role and the testing area.

How it goes
- 01Download NoireMultiplayer.exe and put it somewhere you will find it again. It is the only file you need.
- 02Run it. It checks the current release, updates your game folder, and verifies every file it writes before writing it.
- 03Pick a server from the list and press play. The launcher starts the game on it.
What you will need
- L.A. Noire (2011) on PC — the Steam build, 2675.1
- Windows 10 or 11, 64-bit
- The game installed and run once so it is fully unpacked
- A forwarded UDP port only if you want to host a server yourself
Why it is safe to run
The content delivery network is not trusted; the signature is. It can be replaced, cached, mirrored or breached without becoming a way to run code on your machine.
- Each release ships a manifest carrying the version and a SHA-256 for every file, signed RSA-2048 / SHA-256.
- The launcher carries only the public key. If the signature does not verify, nothing is written — however valid the download looks.
- Every downloaded file is checked against its hash in the manifest, and every path in it is validated before anything touches your game folder.
- Downloads are HTTPS only.
- There is no injection step. The module loads through the ASI loader the multiplayer case already needs, which is also why the same shape works under Proton.
