Four steps cover a first night in Night City with friends. Start with the game version and backup, then install the archive, choose a host world and send an invite. A custom hub is an optional networking choice after the basic setup.

  1. Requirements: Windows 10/11, game 2.5 or 2.31, the matching archive, same build for every player.
  2. Install: unpack into the game folder until the Co-op item exists.
  3. First session: the host opens the lobby and copies the invite, guests join, then everyone marks ready.
  4. Saves: the world is the host save. Guests keep their own campaign files.
Requirements

Loader version, DLC, and OS.

Install

Manual unpack, plus a Vortex branch.

First session

Host and guest clicks.

Saves

Whose file changes.

What works

Quests, photo mode, Sandevistan.

Your own relay

Linux hub, ports, fingerprint.

When it fails

The error table.

Side paths: if the menu item never appears, stop and use the install page. If the server string appears, use troubleshooting before you reinstall. If you want a relay you control, read the self-hosted page after the first session works on Auto: nearest. That order keeps a new group from debugging a hub they do not need yet.

Questions

What is the shortest path to a session?

Match the requirements, unpack the zip, host a session, copy the invite. Saves are the page to read before you care about whose story moves.
