What We Do

Keen Software House was founded in 2010 by Marek Rosa. Marek started as a programmer working independently on the Miner Wars games and the VRAGE engine. After some time Marek was joined by a few volunteers and a real studio was created.

We are an independent game development studio based in Prague, Czech Republic. Our main project is the sandbox video game ๐’๐ฉ๐š๐œ๐ž ๐„๐ง๐ ๐ข๐ง๐ž๐ž๐ซ๐ฌ and our ๐ข๐ง๐ก๐จ๐ฎ๐ฌ๐ž ๐•๐‘๐€๐†๐„ ๐ ๐š๐ฆ๐ž ๐ž๐ง๐ ๐ข๐ง๐ž. The game ๐’๐ฉ๐š๐œ๐ž ๐„๐ง๐ ๐ข๐ง๐ž๐ž๐ซ๐ฌ has sold 5 million copies worldwide. VRAGEโ€™s core feature is volumetricity within the environment.
At this moment we are currently in the Research and development phase, exploring new features of the VRAGE3 engine! Our goal is to support extremely large and fully dynamic and destructible environments, including planets, large spaceships, and any other creations built by the players.

We want to create games that are based on real science, real facts, real physics and real emotions. No magic & fantasy allowed. If we step into the sci-fi area - as we did with Space Engineers and Miner Wars 2081 - we approach it from the hard-sci-fi angle. Every technology and every idea must be explainable using modern-era knowledge with very little extrapolation required.

Why Work For Us

VRAGE3 empowers modders and creators to craft their vision. With an integrated Editor and HUB, the possibilities are endless.
VRAGE3 boasts a dynamic, destructible environment using voxels and block grids, deformable and breakable structures, and vast worlds featuring 100+km planets that are both volumetric and destructible, with seamless travel.
Our engine integrates Havok for physics, showcases planetary-scale volumetric water, and utilizes Object & Data-Oriented architecture, Entity composition, and a Job dependency graph.
We operate on DX12, offering raytraced GI, a GPU-driven pipeline. Designed for PC, Xbox, and PS.
Written in C#, with integrated Editor and HUB, VRAGE3 is focused on empowering modders.

KSWH is a studio with around 100 talented people working all across the world. As a company with a full remote policy we have more than 20 nationalities among themselves.
