A great saga needs all sorts of heroes
Making games is fun! Especially when you do it with people who share the same idea of what makes a good workplace, great.

We design games for everyone, no matter where they are or who they are, and we employ all sorts of people from all kinds of backgrounds to bring them to life. Truth is, we simply can't expect diversity in our players and originality in our games without first nurturing it in our people. A great saga needs all sorts of heroes. And that's it.

We're Seriously Playful
We believe that great gaming experiences happen when they are developed by working in small, autonomous creative teams that control the whole process - from idea to amazing products. Our close connection with the player community gets us instant feedback and enables us to deliver truly magical moments. We value your free time and your need to refuel, relax and find inspiration - by playing games with your colleagues, being at home with your family or going to the gym or out for a run. That's how we stay creative!
