Development

Ed Key began development of Proteus in 2008 in his spare time, he originally envisioned a role-playing game similar to The Elder Scrolls series in which the player would visit towns and fulfill quests but the game only neared its final form when David Kanaga joined development in 2010. . Realizing the extent of the work that would be needed for such a role-playing game as described, the pair decided to make something "nontraditional and nonviolent".

Key developed the game using a game engine he had written in the C# programming language. The developers have expressed interest in allowing player-created mods of the game in the future. After David Kanaga joined the development team as audio composer, the audio mechanics were refined through many different ideas, such as letting players create their own music within the game.

Proteus was released on 30 January 2013 for Windows and Mac, and on 8 April 2013 for Linux. When Proteus pre-orders were open in 2012, an Artifact Edition was also available; including a boxed version of the game with artwork, soundtrack, and notes on the game's development. Ed Key apologized when the Artifact Edition was still in development and unshipped at the end of its release year, and offered to refund customers upon request. As of May 2014 the edition has not been released

Around the time of the game's release, Curve Studios approached Key and later worked with the developers to port the game for release on PlayStation 3 and Vita. These versions of the game use Curve Studio's own game engine. Sony requested that new features be added to the game, though Ed Key said that the company never attempted to steer the direction of the development of these features. Key added location and date-based world generation and a way to interact with the game using the Vita's rear touch-pad. He has stated that the location-specific and date-specific world generation feature could come to the other versions in the future. The PlayStation 3 and PlayStation Vita versions were released on 29 October 2013
