Founded in 2007 by Argi Baltzi, Brain Seal is an independent video game developer and publisher based in the United Kingdom, with games released worldwide across PC, PlayStation, Xbox, Nintendo Switch, iOS and Android.
For nearly two decades, we've turned ideas into games, built worlds, explored genres and brought our creations to players around the world. From dungeon crawlers and gladiatorial combat to strategy and arcade action, our ambition has always been the same: to make games worth playing.
We believe the best ideas don't always have to be new. Great games are built on strong foundations, refined through experience and made better with every iteration. We take what works, build upon it and give it our own identity.
Above all, we believe in independence. The freedom to choose what we create, the courage to make our own decisions and the determination to see our ideas through.
