V1 descends through the layers of Hell, populated by corpses called husks and incorporeal souls, in order to harvest the blood of the various creatures living there. The player controls V1, a machine that uses blood as a fuel source. This results in an angelic Holy Council taking over Heaven in God's stead, damned souls revolting against the Council across multiple layers of Hell, and the extinction of humanity via robotic revolution. In the universe of Ultrakill, God has decided to abandon Heaven, Hell, and the Earth, after discovering humanity has found and is interacting with the Nine Layers of Hell. The game uses retro-style graphics and movement capabilities similar to those of 1990s first-person shooters such as Quake and Doom.

It was released through Early Access on Steam for Microsoft Windows on September 3, 2020. Ultrakill (stylized in all caps as ULTRAKILL) is an upcoming first-person shooter platformer video game developed by Arsi "Hakita" Patala and published by New Blood Interactive.
