Ultrakill has undergone a significant visual overhaul, enhancing nearly every level except the recently added four-level layer of Violence from 2023. Lead developer Arsi "Hakita" Patala showcased the revamped aesthetics of level 1-1, Heart of the Sunrise, and confirmed that while some functional changes may occur, the core geometry and layouts will remain largely intact. A comparison video highlights improvements, including a newly overhauled skybox in layer 2, Lust, which now features a fully rendered 3D city instead of a flat texture. The grotesque atmosphere of Gluttony has been enhanced with new assets, and level 4-3 Ship of Fools has received detailed upgrades. The update also includes two remixed "encore" levels with significantly increased difficulty. Ultrakill is currently available at a 33% discount as part of New Blood's 11th anniversary sale on Steam.
