This was created by him and up until now was being sold as a unity asset for people to buy and develop into things. Google remix software and uFS and see what videos and pics you can find. From the little that is visible to the public on the internet it seems that it will be a simulator based on uFS (Unity Flight Simulation engine). Have a look at the video below and see what you think. So I decided to do a bit of research and it turns out that they are a small (very!) UK based software dev with lots of experience in games development and apparently real time simulation solutions for gaming, aerospace and racing sectors. I've been thinking about what a new sim needs to bring as we have the established ones plus the early access ones (FSW and aerofly FS2) showing great promise.
They are first on at 10am and to be honest I had never heard of them before. So this year Remex software are unveiling a new sim platform at the flight sim show at raf Cosford on Oct 7th.
