Face the night. Choose the right session.
A standalone cooperative adventure in the Elden Ring universe, built around repeated expeditions.
Author-specific setupYour edition, clearly identified.
Platforms shown for the reviewed store edition. A full game’s other releases do not automatically apply to a demo or playtest.
Start with the right package.
Nightreign has community mods, including a separate Seamless Co-op project. Its packages and launch flow differ from the standard protected game. Heimdall does not change anti-cheat settings or route modified files into official matchmaking.
- Use a release explicitly made for Nightreign, not the original Elden Ring.
- Follow the author’s separate launcher, dependency and save instructions.
- Keep a clean standard installation for normal online play; verify compatibility again after an update.
Use the game or author’s installation flow. Automated installation in Heimdall is not enabled for this route.
Keep your setup dependable.
Use the game’s launcher to check for updates and verify files if it fails to start. Keep demo and playtest installations separate from the full game.
Use the platform launcher to start the game. Check the publisher’s current notices after a game update.
