Multiplayer Answers
Direct co-op answers before your group commits to the run.
This hub is for the practical multiplayer questions that come up first: how co-op works, whether the game has matchmaking, whether co-op unlock progress counts, and what makes a stable party.
Use the featured question pages first. Then move into the grouped setup, progress, and party strategy sections when your group wants a more specific answer path.
Popular Co-op Questions

Progress
Use this section when the group wants to know how co-op affects unlocks.
Progress questions tend to be the first blocker for shared learning sessions, so unlock behavior deserves its own direct answer path.
Party Strategy
Move here once setup is clear and your next question is role split or class pairing.
These pages are for groups who already know the mode exists and now want to improve team construction and multiplayer stability.
