BlazBlue: Entropy Effect X

BlazBlue: Entropy Effect X is a 2D action roguelite by 91Act set in the BlazBlue universe. Players take on the role of ACE and, on behalf of the DBS Lab, repeatedly dive into the Sea of Possibility to collect Shards of Possibility and stop the world from collapsing.

The X version combines a new, standalone story with characters and fighting styles from BlazBlue. Astrolabe Games lists 14 playable BlazBlue characters and additional crossover characters from Dead Cells and ICEY.

BlazBlue: Entropy Effect X launched on Feb 12, 2026 on PlayStation 5, Xbox Series X|S, Nintendo Switch and as a native Windows/Xbox Play Anywhere version. The native Nintendo Switch 2 version followed on Aug 13, 2026.

Native X versions are available for PC via Microsoft/Xbox Play Anywhere, PlayStation 5, Xbox Series X|S, Nintendo Switch and Nintendo Switch 2. On Steam, the original PC version BlazBlue Entropy Effect remains a separate product but continues to receive selected content updates alongside the X version.

Each playable character has their own fighting style, which can be developed through more than a hundred individual Potentials. There are also tactical skills that can be freely combined. A core part of the roguelite progression is the ability to transfer skills from developed characters to others, allowing you to build new builds for further dives.

The X version supports online co-op as well as single player. For especially advanced runs, the Extreme Zone offers an endgame area with random elite enemies and bosses such as Takemikazuchi and Hades: Izanami.

In the DBS Lab, researchers try to stop their world from collapsing. ACE is the only one able to dive into the Sea of Possibility and recover Shards of Possibility there. However, each dive brings visions and physical changes, while the truth behind the research project and the collapsing world becomes visible.

The large free autumn update permanently adds the alternative phase 3 route Remains to Mind Training. There and in Mind Challenge, two new strong enemies await: Nine the Phantom combines different elements into magic and summons additional creatures, while the mechanical Lost Gearhulk fights with heavy melee attacks, missiles and a laser from its head core.

The update has been available since Sep 24, 2026 on PlayStation 5, Xbox Series X|S and the Steam version of BlazBlue Entropy Effect. According to Astrolabe Games, the Switch and Switch 2 versions of the X version will follow at a later date.
