The quick answer
Choose multiplayer by activity: private co-op for supported shared content, Online Mode for the broader multiplayer world, and the activity’s own matchmaking for group challenges. Do not assume the entire main story advances for every party member. Check eligibility and reward rules before starting together.

Choose the right kind of session
| Goal | Where to start | What to confirm |
|---|---|---|
| Play supported content with friends | Solo/Co-op session options | The selected quest or activity permits co-op. |
| Join the shared multiplayer world | Online Mode | You are in the intended mode and instance. |
| Run a group challenge | The challenge’s activity entry | Party size, level or Mastery requirements and reward rules. |
| Fight other players | The relevant Arena or competitive entry | Mode rules, queue and regional matchmaking options. |
Prepare the party before travelling
- Agree on the exact activity and who will lead.
- Confirm every player has its prerequisites.
- Create or enter the appropriate session and invite the intended players.
- Check the selected difficulty and activity rules.
- Begin one supported objective and verify the result before committing to a longer run.
Party limits are activity-specific. A general co-op description is not a safe way to infer the size of a raid or competitive team. Use the capacity shown by the activity you are actually entering.
Understand what is shared
Supported Campaign Challenges can use shared progression, but that does not make the complete main-story campaign a shared save. Personal story triggers and activity reward eligibility need to be checked separately.
After the first objective, each player should inspect their own journal and rewards. If someone has no credit, compare the prerequisite, selected mode and completion step before replaying the whole sequence. Being present in the same world is not sufficient evidence that every personal objective advanced.
For exploration, the January update explicitly enabled supported chests, Oddities and some puzzles in Online Mode, with rewards and completion synced to Solo Mode. That is a concrete exception to a blanket “nothing carries over” rule. It still does not turn every personal story step into a shared campaign.
Cross-play and account progress are different checks
The official Xbox FAQ confirms cross-play and shared character data across Xbox, PC, PlayStation and mobile through the same bound account. It also says that an existing account should be bound before creating a new Xbox character; creating that character first can prevent linking to the existing account.
The FAQ limits character-data sharing to the same server region. Separately, the later developer AMA describes cross-region PvP parties using the leader’s chosen matchmaking server. These rules concern different things: moving character progress and selecting a battle server should not be confused.
When joining or progressing fails
Start with the smallest observable issue. If an invitation fails, check the selected mode, party capacity and whether either player is in a restricted activity. If the group enters but progression differs, check each character’s requirements and the activity’s sharing rules.
For poor combat responsiveness, compare the chosen battle server and the players’ connection conditions. Do not immediately rebuild your character to solve what may be a session or latency issue. Once the session works, keep a short note of the successful setup for the next group run.

Common questions
Can we play the entire main story as one shared campaign?
Do not plan on that. Co-op support and shared rewards are activity-specific; main-story progress includes personal sections. Choose explicitly supported content and verify each player’s progress.
Why did a chest count but my friend’s story quest did not?
Collectible sync and story completion use different rules. Check the quest’s own co-op eligibility and your personal prerequisites. A collected chest proving that world progress synced does not prove the nearby story conversation can be completed as a guest.
