Kris and his team did a fantastic job on this project. Very efficient, great level of professionalism, high standard of work, and outstanding value for money. Our project was a large scale MMOG built in Unity. Kris and his team also helped with the Steam Greenlight process and our game was successfully Greenlit in just one week, an incredible achievement. We'll be looking to use them again in the future whenever we have the possibility to do so!
