Doom Eternal has been review-bombed over the weekend, as disgruntled players took to Steam to show their thoughts on the the game's Update 1. The issue isn't in the update itself or it changing core gameplay functions; rather, it's based on the inclusion of Denuvo's Anti-cheat mechanism for the multiplayer component of the game, which is also running in the single-player campaign - considered to be the core of any Doom game.

Players are against the inclusion of Denuvo and its monitoring subroutines due to it having a a kernel-level service that monitors gameplay. Gamers are noting performance decreases, framerate drops, crashes, and deleted Saves after the game's latest update. Others are voicing their discontent at the fact that Denuvo has been added post-purchase of the game; players that might not choose to buy the game over that detail have already bought it, and refunds are apparently not being entertained. Doom Eternal's previous 90% user review score on Steam now stand at a measly 50%, which is absolutely undeserving of the game itself. Doom may be Eternal, but its community feedback sure isn't.
