The answer first
The entire game is officially playable in co-op, including exploration, quest choices, and shared spoils. Update 6 says co-op quests track the host and includes fixes for client inventories, recreated quest tabs, and wiped progress. Hotfix 5 also added teleporting through a teammate’s map marker. Recent players still report desync and reconnect problems, so this is a dated status guide—not a stability guarantee.
What co-op officially includes
Steam lists online co-op, shared/split-screen co-op, Remote Play Together, and single-player. The official description says the whole game can be explored together and quest consequences belong to the group.
Treat the host as quest-state authority
Update 6 says co-op quests track the host and lists fixes for client quest reconstruction, inventory restoration, multiplayer state loading, and wiped progress.
- Record who is hosting before a quest.
- After reconnecting, compare the host journal with the guest tab.
- Confirm both inventories before handing over a unique quest item.
- Keep a save before a choice-heavy or previously reported quest.
Teammate teleport is not normal fast travel
Hotfix 5 added teleporting through a teammate’s map marker. This does not prove every discovered world location supports ordinary fast travel.
If players desync
Recent reviews mention rubber-banding, inventory mismatch, quest-state problems, or rejoining sessions. These reports do not establish one universal fix. Record patch, host, quest, item state, and reconnect result.
