Doom Eternal is a great game. Having played through it recently myself, I’ve been considering going back for some Ultra Nightmare runs and maybe (but probably not) playing more of the weird asymmetrical multiplayer mode.
Well, now I’m not so sure either of those will happen.
In what is listed as a “feature” on the official website, and described further in this wonderfully tone-deaf news post, Doom Eternal now boasts everyone’s favorite addition to a primarily-singleplayer experience: Denuvo Anti-Cheat. This third-party kernel-mode driver will start up and close with the Doom application, and can also be uninstalled at any point. But, according to users online, the game forces players to re-install it when booting up — even just to play the singleplayer campaign.
