GRIEF
GRIEF is an upcoming 2.1/2.2 Extreme Demon mega-collaboration hosted by IcEDCave, created by DrCuber, Doop, GhostVandalf, Iris, CDMusic, MercuryDT, RealVet, Triplash, Greafer, GrenadeOfTacos, Rynoxious, Burgadahz, and NineDice, and set to be verified by Doggie[1]. It is an extended, possible remake of IcEDCave's 1.9 impossible level Slaughterhouse and the prequel to his 2.1 Extreme Demon with the same name, Slaughterhouse. The level features an art-based hell theme, revised gameplay based on the original, and an extension from the original over a minute long.
GRIEF is set to be the hardest level in the game, competing against many other upcoming levels.
History
See also: Slaughterhouse
In late 2015, IcEDCave published his level Slaughterhouse, a hell-themed impossible level consisting of simple decoration and extensive impossible spam. The level was showcased on YouTube by ToshDeluxe on 3 October 2015, becoming one of his most popular videos.
From 2019 to 2021, IcEDCave hosted an unrelated Extreme Demon level also titled Slaughterhouse. This level was initially hack-verified by spaceuk and placed at #1 on the Demonlist before being verified by Doggie.
Doggie began to publicly practice for the verification of the level on 2 May 2024, achieving his current best run of 65-83% on 7 May 2024 and a record of 10% on 9 May 2024. In his initial streams, he used Click Between Frames, a recently released Geode mod to remove limitations in the game's input polling rate, citing that the level would be nearly impossible to verify in its present state with the 240hz maximum tick rate implemented in 2.2; along with Diamond and NothingIsScary, he uploaded a video on 7 May 2024 urging RobTop to implement the mod's mechanics into the vanilla game[2].
