ULTRAKILL

ULTRAKILL is a deliberately structured Early Access game built around Dante's Inferno, with each major update adding a new "Layer." The game has received a steady stream of major content updates since its September 2020 Early Access launch: Layer 4 (June 2021), a secret levels update (April 2021), Act 2 with Layers 5 & 6 (August 2022), Layer 7 (December 2023), a full arsenal update (April 2024), the ULTRA_REVAMP overhaul (February 2025), and most recently Layer 8: FRAUD (February 25, 2026). Layer 8's launch was notably successful — the developer reported peak concurrent players of 72,000, nearly triple the Layer 7 launch. Since shipping Layer 8, the developer has continued actively patching the game with multiple hotfixes and balance updates through April 2026, the most recent being April 25, 2026. The game has not reached 1.0 and the developer has not announced a completion date. Given the Inferno-inspired structure (which has nine circles of hell), additional layers beyond Layer 8 are expected before the full release. The developer has maintained a consistent pattern of shipping major content and immediately supporting it with patches — a pattern that remains active as of April 2026.
