Geometry Dash Slaughterhouse is a 2.1 Extreme Demon mega-collaboration by IcEDCave that has been hack-verified by Spaceuk.
When Geometry Dash Slaughterhous, Firework, and Arcturus were all graded on October 29, 2021, there was some uproar about the levels' demon ratings. First, both Firework and Slaughterhouse were rated as Easy Demons. The levels, however, were rated differently, with Arcturus being an Easy Demon and Slaughterhouse/Firework being an Extreme Demon. An hour later, Arcturus was upgraded to Extreme Demon.
The level starts with a slow mini-cube section that serves as a build-up. 'IcEDCave OG Slaughterhouse' appears as text. 'Welcome to the End of the World,' says a Clubstep monster as it approaches the player. The player must hop over a few spikes that are spaced out. The screen then goes black, and the player is transported to another section with similar gameplay. This component is a standard-size cube with narrow-spread triple spikes and an orb timing. As the screen turns black, another Clubstep monster appears at the end of the section.
