What is Gbanga, Millform Inc?

Gbanga, Millform Inc is a studio that focuses on the development of mixed-reality games and playful experiences that operate at the boundary between reality and digital fiction. That is games that analyse the player’s current situation such as location, local weather and friends nearby to deliver a game experience that is more fun.

Our most renown games include Urban. Hunt., the world’s largest massive-multiplayer geo-game, Galaxy Invaders, a VR arcade game, Gbanga Famiglia, a mafia-themed game where players compete over real-world establishments like bars and restaurants and extend their territory on a shared global map.

When was Gbanga, Millform Inc founded?

Gbanga, Millform Inc was founded by Julio Perez and Matthias Sala, two computer scientists from Swiss Federal Institute of Technology ETH Zurich in 2007 in Switzerland. After working on mixed-reality games for the pre-smartphone area, we have started to create mixed-reality games for iOS, Android, HTML5, HTC Vive and other platforms.

What is the meaning of the name?

Our trademark Gbanga is based on a town in Liberia which is spelled GbaRnga. Because our mixed-reality games are often based around locations, we picked a name of a location far, far away.

The name of the Swiss registered company Millform Inc is based on the Italian words mille and forma and literally means thousands of designs. Millform Inc. owns the trademark Gbanga.
