D4 Studios is an indie portuguese developer, founded in Lisbon in 2021, by the programmer Pedro Marques and artists Gabriel Santos, Gonçalo Vila Verde and Pedro Bezerra.

The first three members already worked together, having developed small projects such as Inner Mind – a 1st person Puzzle/Adventure and Asashin - a 3rd person Action/Adventure, bringing the team already some experience in PC development.

Before joining D4 Studios, Pedro Bezerra had also worked on similar projects such as Timefall – a 1st person puzzle/adventure and 3rd person Remains of Light - Action/Adventure.

With this in mind, the team now decides to bet on its most important title, and the team's biggest project to date, Runewatch: Age of Arcanum. The videogame arises from a partnership with the Lusófona University of Humanities and Technologies course: Degree in Video Games.
