--- title: "State of the Net: everything built so far" date: "2026-08-25" description: "A technical recap of everything OPEN//77 has built: multiplayer replication, dedicated servers, the Warden panel, Lua scripting, accounts and the launcher." tags: ["recap", "multiplayer", "platform", "servers"] --- This is the first post of the OPEN//77 devblog. From today on, a post lands here every working day, summarizing what actually shipped in our **Cyberpunk 2077 multiplayer mod** — written for players and server owners, with a bit more technical depth than the daily Discord summaries. Since it's day one, here is the big picture of what already exists. ## The game is real multiplayer OPEN//77 puts other players in your Night City. The core of the project is a native client module and a dedicated server speaking a custom replication protocol, and by now that protocol carries most of what makes a session feel shared: - **Players** — movement, animation and emotes replicate between clients, so other players look like players, not sliding mannequins. - **Combat** — gunfights, melee and even grenade flight are synchronized, including combat audio. PvP has been through live regression testing between real clients. - **Vehicles** — full vehicle replication: drivers and passengers, authoritative vehicle damage, and owner-state sequencing so two clients never fight over who controls a car. - **The world** — time of day, weather and world destruction replicate. Destroyed props stay destroyed for everyone in the session, elevators and moving platforms stay in sync, and the single-player population is sanitized out of the way so the server decides who lives in the world. All of that runs on dedicated servers — sessions are hosted, not peer-to-peer, and the server is authoritative over the world. ## A platform, not just a mod Around the game sits a full online platform: - **Accounts** — you sign in with an OPEN//77 account. E-mail verification and password reset work end to end, backed by the master server that also keeps the server directory. - **The launcher** — a native desktop launcher handles browser-based sign-in, verifies your game installation, keeps the mod up to date through signed auto-updates, and updates itself the same way. One click on a server takes you from the launcher straight into that world. - **Direct connect** — `open77://` deep links boot the game directly into a chosen server, from the website, Discord, or anywhere a link can live. - **Server browser** — a live server list exists both in-game and on this site, with per-server detail pages, icons and banners. ## Server owners get first-class tools Running a world is meant to be a product experience, not a folder of config files: - **Dedicated servers for Windows and Linux**, shipped as versioned builds with a first-run setup wizard that walks through licensing and configuration. - **Warden**, the web admin panel: a config editor with validation, live Lua resource uploads that hot-reload without a restart, announcements, scheduled restarts, multi-user access with custom roles, and a full audit trail. - **Lua scripting** — servers are scriptable in Lua against a documented API (browse it under [/docs/api](/docs/api)), with MySQL bindings for persistence and a freeroam gamemode shipped as a reference resource — the same foundation a co-op world or a Cyberpunk 2077 RP server builds on. - **Moderation** — server-issued bans and platform-level enforcement are wired end to end, from the in-game action to the master server's records. ## Security, in broad strokes A serious slice of recent work went into keeping the network fair: signed builds with server-side verification, client integrity checks, and platform-level enforcement against tampered installations. We deliberately don't blog implementation details here — but the goal is simple: when the doors open, playing legit should be the only practical way to play. ## What's next This entry records an early development milestone.
