Do this first

Fast checklist

  1. 01

    Make sure every player has the current update installed.

  2. 02

    Choose content that currently displays multiplayer support.

  3. 03

    Create a lobby and use the available friend invite interface.

  4. 04

    Confirm every player appears in the live lobby before starting.

  5. 05

    If entry fails, remake the room and keep the leader active while waiting.

What the official listing confirms

The Steam store listing includes Online Co-op. The official patch notes also discuss lobbies, party entry, Quick Entry, and multiplayer party behaviour. Those are the facts this guide is built on.

What we cannot confirm for you

Our checked official sources do not spell out a fully shared campaign or open-world co-op structure. We therefore do not promise that your whole story progression can be played together. Use the multiplayer marker and the current activity lobby to decide what your group can enter now.

If an invite works but your friend never enters

Update 1.0.9 addressed an intermittent party-entry problem and long lobby loading. Update everyone, remake the room rather than reusing a stuck one, and make sure the leader has not been idle long enough to trigger the party-disband behaviour noted in 1.0.10.
