Fatal Claw v1.0.54 Hotfix

v1.0.54 is a hotfix released on 10 September 2026 for Fatal Claw 1.0. This update delivers quality-of-life improvements to movement systems, adds mouse button customization, revises dialogue for clarity, and introduces new system guides for the Stone of Narrative and Epilogue. This page documents the confirmed changes.

See Updates Hub for the full version history.

What v1.0.54 adds and improves

Improved wall-climbing controls

Kisha now transitions more smoothly into wall climbing when coming into contact with a wall while moving.

This improvement addresses a common player complaint about the wall-climbing initiation in Fatal Claw. Previously, players reported that Kisha would sometimes fail to grab a wall when running toward it, particularly in precise platforming sections. v1.0.54 makes the transition more forgiving, allowing Kisha to latch onto walls more reliably when moving.

This change benefits navigation throughout the underground, especially in vertical sections of Elord Castle, Origin Laboratory, and the Higasha Tenshukaku Interior.

Improved pogo bounce interactions

Pogo bounce interactions have been improved with the following monsters and bosses:

• Sorr Warrior
• Crimson Wolf Warrior
• Heavy Infantryman
• The Frost Wolf
• Sorron

The pogo bounce mechanic — bouncing off enemies with a downward attack — is a core mobility technique in Fatal Claw. v1.0.54 refines the bounce physics and hit detection for these specific enemies, making chained pogos more consistent and reliable.

For Sorron specifically, the improved pogo interaction makes his floating-blade phases more manageable. Players who were having difficulty reading his attack patterns during pogo sequences should find the encounters more predictable after updating.

Mouse button support

Added support for assigning mouse buttons to game actions.

v1.0.54 introduces customizable mouse button bindings, allowing players to assign actions to their mouse’s additional buttons (typically the thumb buttons on the side of the mouse). This is a highly requested feature for players who prefer mouse-and-keyboard control schemes.

Players can now rebind healing, floating, and other core actions to mouse buttons, improving accessibility and allowing for more personalized control configurations.

Dialogue revisions

Revised certain dialogue to make the content easier to understand.

The v1.0.54 dialogue pass improves clarity across multiple story segments. This addresses feedback from players who reported confusion about certain narrative points or character motivations. The revisions are designed to maintain the story’s depth while reducing ambiguity.

Stone of Narrative system guide

Added a system guide for the Stone of Narrative.

The Stone of Narrative is the objective tracker that shows what the game remembers and what it still wants from you. v1.0.54 adds an explicit system guide that explains how the Stone works, what its categories mean, and how to use it effectively throughout your playthrough.

This guide is particularly helpful for new players who may be unfamiliar with objective-tracking systems in Metroidvanias. It clarifies that some objectives are mutually exclusive and explains how to identify which choices lead to which outcomes.

Epilogue system guide

Added a system guide for the Epilogue.

The Epilogue is the content that continues after the ending credits roll. v1.0.54 adds a dedicated system guide that explains what the Epilogue contains, how to access it, and what carry-over mechanics affect it.

For players pursuing all endings or working toward the 35-cycle completionist path, this guide helps clarify the Epilogue’s role in the overall narrative structure.

Wheel of Fate visibility improvements

Improved the visibility of the Wheel of Fate.

The Wheel of Fate is how Fatal Claw handles New Game Plus — returning you to the beginning after credits while keeping certain progress. v1.0.54 improves the visibility of this mechanic, making it easier to locate and understand after reaching the ending.

This change helps players who may have missed the Wheel of Fate on their first playthrough or were unsure about its function when they encountered it.

Golden Claw achievement guidance

Improved the guidance for the achievement related to obtaining the Golden Claw.

The Golden Claw is a named weapon upgrade that requires specific steps to obtain. v1.0.54 adds clearer guidance toward this achievement, reducing the confusion that many players experienced when trying to locate or trigger the acquisition sequence.

Journal and Archive progress filters

Added progress-based filters to the Journal and Archive.

The Journal tracks story events, character encounters, and lore entries. The Archive contains collected information about game systems, enemy types, and world lore. v1.0.54 adds progress-based filtering to both, allowing players to quickly see which entries they have completed and which remain.

This quality-of-life improvement makes it easier to track collectibles and lore entries without manually checking each category.

What v1.0.54 does not change

This is a quality-of-life and polish update. It does not:

• Add new regions, bosses, or story content
• Change game balance, damage values, or enemy health
• Modify the Steam Deck Playable status
• Alter the four launch regions from Version 1.0
• Address any controller binding issues beyond mouse support

After v1.0.54

This hotfix represents the latest round of post-launch improvements from NDEV GAMES. The wall-climbing and pogo bounce refinements address two of the most common player concerns from the first weeks of release. The new system guides for Stone of Narrative and Epilogue help players navigate the game’s more complex narrative mechanics.

The mouse button support is particularly valuable for players who primarily use mouse-and-keyboard, giving them the same customization options that controller users have enjoyed since launch.
