Hi-Fi Rush is ditching its Denuvo anti-tamper software as part of developers' Tango Gameworks transition to working under new owners Krafton. A fresh patch has been released swapping logos to reflect that switch in management, and you'll need to install it before mid-January if you want the game to stay playable.
Krafton, of course, bought up Tango after the studio's former parent company Microsoft announced plans to shut it down back in May, alongside Redfall developers Arkane Austin and Mighty Doom creators Alpha Dog Games.
