Soul Interface is a first-person idle life sim game developed and published by soulless technologies.

Formerly Hound, Soul Interface was released as a demo on Steam in May 11th, 2024. The game released to Early Access on Steam on October 24th, 2024.

As of July 2024, Soul Interface has been receiving consistent updates to improve stability. There exists instability with non-essential mechanics, like containers not being able to be deleted or complex atoms disrupting symmetry. Crashing is common, and it's recommended to save often by frequently closing the game. Quicksaving by pressing F5 will also work, but isn't recommended as that may cause additional instability.
