Myastere: Ruins of Deazniff

Metroidvania-style “spring wire action” game Myastere: Ruins of Deazniff will launch for Switch via the Nintendo eSoph and PC via Steam on April 15, publisher Digimerce and developers Success and Studio Saizensen announced. It will support English, French, Italian, German, Spanish, Latin American Spanish, Portuguese, Brazilian Portuguese, Russian, Japanese, Traditional Chinese, and Korean language options. Voice-overs are Japanese-only.

Here is an overview of the game, via its Steam page:


There are still ruins in the world that no one knows about.

In the year 20XX, in a dark forest in a certain country.

In a dark forest in a certain country, the Kingdom’s Intelligence Department discovers the source of “Myastere,” a magical substance with a noxious miasma that emanates from this world.

The Kingdom decides to dispatch the Royal Special Relics Investigation Department, a specialized organization to investigate the source of Miasteel.

Aura Mowkish, a member of the 3rd Research Department’s research team, went to the site to investigate.

The animals had become rabid due to the high concentration of Myastere, and the ruins were being exposed by a group of thieves known as “Deazniff.” Seeing the devastation, Aura’s heart quietly lit up with frustration.

He dodged the Deazniff and the mad beasts and, relying on his revolver and wires, proceeded to the depths. In the depths of the earth, there were ruins of a different civilization than before.

Obstructed by the deepening mystery and the world-eating Myastere, Aura still does not know. Aura still doesn’t know about the shadow of the Holy Order, which has fallen to the ground and is no longer mentioned in the official history.


Myastere: Ruins of Deazniff is a 2D spring wire action game that unfolds in all directions across the stage.

As a member of a special ruins investigation team, you start your investigation in the vast underground world, making full use of steampunk-dressed guns and wire projectors.

Gather historical relics “Relics” and dive into the mysteries of the ruins by dodging looming mad beasts, “Deazniff” thieves, and even more beyond-human enigmas.

Step into the deepest part of the ruins, eliminate the evil lurking in the ruins as it is gradually revealed, and aim to complete the mission!
