What the Official Store Confirms
The Steam store confirms four-player online co-op, item exchange between players, and the ability to revive downed teammates. This is a core feature of the shipped game, not a post-launch addition.
Players are normally restricted from joining multiplayer lobbies that are ahead of their own main-story progress.
Creating and Joining Games
The Steam store lists Online Co-op as a feature; the exact lobby flow (invites, searching, or matchmaking) should be confirmed on the official store page or in the current build before describing it as fact.
If you are joining another player's game, keep in mind that progression rules for your solo save, loot ownership, and story sync are not published in official materials. Confirm them in the current version.
Progression and Currency
Exact rules for how progression currency is awarded per boss, per run, or in co-op are not published in official materials. Do not assume failed runs always grant currency or that all players receive full rewards.
The official store confirms the core co-op loop: the party descends the tower together, exchanges items, and revives teammates. Details beyond this should be checked in the current version.
Reviving Teammates
The official store confirms teammates can be revived in co-op. Specific revive timing, downed-state rules, and checkpoint behavior are not published and should be verified in the current version.
In practice, coordinate roles when someone goes down — typically the player closest or the one with the most mobility attempts the revive while others create space.
Trading Items and Solo vs Co-op Differences
The official store confirms item exchange between players during co-op. Coordinate builds at the start of a run so everyone knows what to look for and who gets what.
Solo and co-op play feel different: in solo you control all decisions and pacing, while co-op adds shared aggro and coordination needs. Whether enemy scaling, loot ownership, or progression sharing differ between modes is not published — verify in the current version.
