A fan-made mod called OPEN//77 entered open alpha on November 7, adding dedicated multiplayer servers to Cyberpunk 2077 for the first time since launch. The project lets anyone host or join a persistent server running custom roleplay rules, racing modes, or player-versus-player content — all built by an independent community team with no involvement from CD Projekt Red.
What OPEN//77 Adds
OPEN//77 works on the same model as FiveM, the long-running fan platform that turned GTA 5 into a roleplay hub. Instead of a single shared online mode, server owners run their own instances and write custom rules in Lua 5.4, the scripting language the mod exposes through its API. Resources — the mod's term for individual scripts or features — reload on the fly, so server admins can push changes without restarting the whole session.
The mod's current scope covers roleplay servers, racing, and PvP, with support reportedly in progress for larger persistent-world features. A standalone Windows launcher handles the technical side: it verifies your existing Cyberpunk 2077 install, downloads and updates the mod files, and surfaces a browsable list of active servers to join.
OPEN//77 isn't the only project chasing multiplayer in Night City. CyberMP, a separate mod, ran a semi-open test that reportedly held 30 to 40 concurrent players without issue, while NightCoop takes a narrower approach — letting up to eight players run through the main campaign together as separate versions of V. OPEN//77 is the first of the three to reach a public alpha with dedicated RP server infrastructure built in from the start.
What You Need to Install It
OPEN//77 requires a legitimate, Steam- or GOG-purchased copy of Cyberpunk 2077 running version 2.5 or later with the Phantom Liberty expansion installed. The team behind the mod has said pirated copies aren't supported. The mod itself is free, distributed through the project's own site and GitHub page rather than a storefront.
Because this is an open alpha, expect rough edges. Server stability, moderation, and content depth vary by who's running the individual server you join — there's no central authority enforcing rules the way there would be on an official platform.
Where CD Projekt Red Stands
OPEN//77 is explicitly unofficial. Its own documentation describes it as an independent project with no affiliation or endorsement from CD Projekt Red, meaning uptime, rules, and moderation are entirely in the hands of whoever hosts a given server.
CD Projekt Red did plan an online multiplayer mode for Cyberpunk 2077 at one point, but the studio shelved it after the game's rocky 2020 launch and years of recovery work on the single-player version. The studio has not commented on OPEN//77 specifically, and it's unclear whether the mod will draw the same kind of tolerance Rockstar has shown toward GTA's FiveM scene, or a more restrictive response. For now, Night City's first taste of persistent multiplayer is coming entirely from fans, not from CD Projekt Red.
