Mainframe – Building the game of a lifetime
Building a virtual world that millions will live in, for decades.
Mainframe is an independent, venture-backed game developer. Our team is bringing together veterans from places like CCP, Next Games, Blizzard Entertainment, Ubisoft, and Remedy. We’re set on creating a social sandbox MMO, where players will build their personal home and craft their fate.
It’s the game of a lifetime.
Our story
Founded by veteran developers from Iceland and Finland, Mainframe has assembled a team coming from all corners of the industry, places like CCP, Remedy, Next Games, Rovio, Ubisoft, and Blizzard Entertainment. We bring all our hard-won lessons (both good and bad) to our cause of reimagining an MMO for this decade.
Our aim
To create a persistent social world that reflects the best strands of our collective DNA as game developers, forging a fresh take on a storied genre with a game that our players will call home, whether they choose to access our world from their PC, console, or phone. We aim to be one of the first studios to create an experience made for the new medium that is cloud gaming.
The right company
Reaching this destination promises to be quite a journey, and we have the firm intention of enjoying it. We’re designing Mainframe to be a human-sized, warm and welcoming place, at the heart of which is the conviction that empowerment of individuals and teams is the best way to let our common passion for our project shine. Sounds like the right fit for you? Check out our job openings.
