Founded in 2023 by brothers Suleyman (Sol) and Tamerlan (Tam) Tahirli, is an innovative VR focused game development studio. The Tahirli brothers arrived in Canada as child refugees from Azerbaijan, and playing and making games together has always been a source of comfort and connection for the two. Sol has always focused on game and graphics design, and Tam honed his skills in scripting for third-party mods in games such as RuneScape and the GTA Series. In 2021, they embarked on a new journey together, developing a VR game as a means of connecting during the pandemic. This project ultimately evolved into ZIX, Hidden IO's flagship title.
