Open//77 Mod Brings Massive Multiplayer Chaos to Cyberpunk 2077

While Cyberpunk 2077 was originally slated to receive an official multiplayer component, those plans were ultimately scrapped following the game’s difficult launch. However, a new project titled Open//77 is looking to fill that void by transforming the single-player experience into a massive, GTA Online-style playground. According to a report from IGN, this ambitious mod has officially entered its alpha stage, allowing players to jump into servers supporting over 100 people at once.

The Shift to Multiplayer

Unlike the previously released NightCoop mod, which focuses on letting up to eight friends play through the main story campaign together, Open//77 is designed as an open-world sandbox. It introduces new tasks, roles, and features not found in the base game, including an expanded vehicle customization menu and third-person perspective gameplay. Players can engage in various activities, ranging from races and contract work to group activities like hanging out in rented private rooms.

The mod supports a wide variety of server types. The most popular of these, NCRP, aims to host up to 1,000 players for dedicated roleplay sessions, while others are built specifically for combat and PvP encounters. Users can join these servers and, in some cases, automatically download the host’s mods to ensure compatibility, though the experience may vary if you already have a heavily modified game installation.

AI Development and Community Impact

Open//77 has sparked conversation regarding its development, as the creators openly acknowledge using AI in their process. This has become a point of contention within the broader modding community. As reported by IGN, this trend of AI-assisted development has led platforms like Nexus Mods to implement mandatory disclosure rules, allowing users to filter these mods out of their search results if they choose.

Why it matters

For fans of Night City, Open//77 represents the most significant attempt yet to bring a persistent, large-scale multiplayer experience to the game. If you own both the base game and the Phantom Liberty expansion, you can now participate in these player-run servers to experience social features like car meets or roleplay scenarios.

Because this project is in an early alpha state, players should be prepared for potential instability, especially if they are running other mods simultaneously. As the developer CD Projekt Red continues work on the sequel to Cyberpunk 2077, these fan-made projects remain the primary way for the community to experiment with multiplayer gameplay in the current iteration of the engine.
