Command a line-up of unique characters from the renowned BlazBlue franchise and dive into an unparalleled action experience.

At a mysterious domain, known as “the Lab”, a group of elite researchers race to save a collapsing world; however, despite their efforts to date, Dr. Mercurius, head of the laboratory, still warns the world’s downfall is near.

In a last-ditch effort, the urgent Research of Possibility initiative seeks to collect Shards of Possibility – a special fragment of the world that could forestall the seemingly inevitable destruction. These shards lie within the Sea of Possibility, a realm between worlds, beyond the bounds of reality.
The protagonist, Ace, is the only being capable of diving into this sea. Guided by the elite researchers at the Lab, Ace descends again and again in pursuit of salvation—until strange visions take hold and his body begins to change.

As Ace continues to dive, countless memories flood his mind, and the truth behind the collapsing world – and the research itself – begins to surface....

“……The Power of Azure.”

Astrolabe Games is excited to announce that Fall 2026 free major update arrives today for BlazBlue Entropy Effect X.

The update introduces two new elite enemies, Nine the Phantom and The Lost Gearhulk, alongside the new stage “Remains”. A brand-new launch trailer is released to celebrate the long-awaited free update.

*Note: The update for Nintendo Switch and Nintendo Switch 2 Edition will be released at a slightly later date very soon.

A Storm of Spells — New Elite Enemy Nine the Phantom Arrives

The powerful opponent Nine the Phantom joins the game as a new elite enemy, challenging players to an intense showdown.

Nine can attack by casting individual element spells or combine different elements to unleash a variety of devastating spells. In addition to her extensive magical arsenal, she can summon powerful familiars to aid her in battle. To deal with her relentless attacks, players must carefully read her changing attack patterns, time their dodges, and find openings to strike back amid the magical onslaught.

Enter “Remains” and Confront The Lost Gearhulk

The new stage Remains is now available. Buried deep within it lies The Lost Gearhulk, an enormous machine that stands as a formidable obstacle in your path.

The Lost Gearhulk swings its massive arms to deliver crushing blows, while missile bays across its body can unleash dense barrages in an instant. Even destroying both arms is far from the end of the fight. A core concealed within its head can continue the assault with powerful laser attacks.

BlazBlue Entropy Effect X is available for Nintendo Switch, Nintendo Switch 2, PS5, and Xbox Series X|S at $24.99 / €24.99.
