Current multiplayer answer
Moonlight Peaks is currently a single-player game. Steam lists Single-player, full controller support, Steam achievements and Steam Cloud, but no online co-op or multiplayer feature.
The life-sim structure may look suited to co-op, but feature requests and player wishes are not evidence of a released mode.
How to verify a future change
- Open the official store page for your platform.
- Check the feature or play-mode labels, not only the game description.
- Look for an official update announcement naming co-op or multiplayer.
- Do not install unofficial multiplayer downloads that request your account credentials.
Check the current Steam feature list.
Checked July 18, 2026: Steam lists Single-player and does not list co-op or multiplayer.
