For PC players, please review the following information regarding upcoming changes required for continued service use. ■ Notice on Upcoming Denuvo Removal Denuvo support for the PC version of Hi-Fi RUSH is scheduled to end at 00:00(KST) on January 16, 2026. Please note that even after Denuvo is removed, the game’s own anti-tampering features will remain active and will not affect normal gameplay. This adjustment is intended to provide a more stable and efficient service environment.
I assume it just means the game won’t launch anymore after that date if you don’t update since denuvo can’t be contacted anymore.
