Crimson Moon supports solo play and two-player online co-op. Launch matchmaking includes Quick Match and direct Join Codes, with full cross-platform play across supported platforms.
How to Start Co-op
- Return to Sanctus Clypeus, which functions as the party lobby.
- Invite a friend, select Quick Match, or enter a Join Code.
- Confirm both Loadouts and Angels in the shared hub.
- Select the next Mission at the War Table.
- Return to the same hub together after the Mission.
Crossplay and Platforms
Players on different supported platforms can connect directly through full cross-platform play.
How disabling crossplay affects Quick Match availability, and whether Join Codes still work, needs hands-on testing.
Shared Hub and Progression
Partners return to the same Sanctus Clypeus lobby rather than being separated. Both can continue adjusting Loadouts, using hub progression features, and speaking with NPCs before the next assignment.
Official sources confirm that solo players can access all story content, enemies, levels, and equipment. Co-op adds tactical options but does not gate content.
Co-op Build Tips
There are no formal team-up moves. Gear, Weapon Arts, Boons, and status effects provide the main co-op interactions. One player can apply a Mark or status effect while the other uses Gear that benefits from it. In a Freeze build, both players can help build Freeze before one focuses on Shatter damage.
- Decide who applies the status effect and who triggers the payoff before the Mission.
- Avoid competing for the same narrow combat role.
- Cover damage, control, and survival across both builds.
- Recheck how the builds work together after major Gear changes during the Hunt.
Scaling, Revives, and Loot
Co-op uses shared lives and partners can resurrect each other. Bosses scale for the second player's damage and utility, but exact revive timing, health values, host and guest rewards, and item-sharing behavior still need hands-on testing.
The launch issue list warns that Mission progress may not always be awarded correctly to the host during co-op play.
Launch Co-op Known Issues
ProbablyMonsters is preparing Hotfix 1.0.1. As of September 2, 2026, the official known-issues list includes occasional false “Player has left the session” messages, freezes or disconnects in Moore Manor, players stuck on the title screen after accepting an invitation, and Mission progress not always being awarded to the host.
The issue list is time-sensitive and may change after the first hotfix. PlayStation 5 and Epic Games Store Friends List UI problems are also acknowledged.
