Netmarble is introducing dedicated sound features for visually impaired players in its open-world RPG under development after accepting a suggestion from a visually impaired user overseas.

Netmarble said on May 22 it has applied accessibility features in Seven Deadly Sins: Origin for visually impaired and low-vision players.

The feature addition was prompted by a letter sent in April by a visually impaired user in Japan, written in braille and word processing format, to Netmarble. In the letter, the user shared impressions of sound-dependent gameplay using ambient sounds and background music and proposed a feature that guides the distance and direction to objects through sound.

Developers at Netmarble F&C reflected the feedback and created an in-game "sound class exclusively for visually impaired players" feature. When enabled, it provides warning tones for monster attacks and low character health and adds dedicated sound effects to help identify the location of treasure chests.

Netmarble also plans to update the game with a feature that assigns key objects to the keyboard number keys and, when a specific button is pressed, provides the direction and location information of the nearest object through voice or alerts.

Netmarble is also steadily collecting feedback from global users, including receiving a handwritten letter from a user in the United States containing positive comments about gameplay and character implementation.

Seven Deadly Sins: Origin is a game based on the original intellectual property that has recorded cumulative global sales of 55 million copies, and will be available on PlayStation 5, Steam, Google Play and the Apple App Store.

A Netmarble official said the goal is to create an environment where anyone can enjoy games without barriers by listening to users' sincere voices. The official said the company will continue to improve the game's completeness and accessibility based on user feedback.
