BlazBlue Entropy Effect is a fast-paced 2D action roguelike developed by 91Act and licensed by Arc System Works, offering a fresh spin on the BlazBlue universe. Released globally on January 31, 2024, for PC, with a mobile launch on July 22, 2025, the game introduces an original storyline set in a chaotic future where humanity seeks salvation through a cyberspace program called ACE. Players take on the role of an ACER, navigating simulated battles to uncover the truth behind the mysterious Entropy Effect.
Gameplay centers around the Mind Training mode, a roguelike loop where players choose from a roster of ten playable characters—including Ragna, Noel, Hakumen, and Mai—each with distinct combat styles and upgrade paths. As runs progress, players unlock Legacy Evotypes, allowing them to pass down skills and modifiers to future characters, creating a layered progression system that rewards experimentation and mastery.
Combat is fluid and responsive, with combo-heavy mechanics, elemental effects, and skill inheritance that make each run feel unique. The cyberpunk aesthetic blends dramatic sprite animations with neon-lit environments, while crossover content with titles like ICEY adds extra flair. Though the story is separate from the main BlazBlue canon, it explores philosophical themes of identity, memory, and survival in a collapsing digital world.
