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.
Quick answers
FAQ
Can friends play the whole campaign together?
The checked official sources do not confirm a fully shared campaign. Check the multiplayer marker and lobby for the activity you want to enter.
What if a friend invite works but entry stalls?
Update everyone, remake the room, and keep the leader active. Official 1.0.9 and 1.0.10 notes address party entry, lobby loading, and leader inactivity.
