Atomkrieg, ja bitte
This is the first time I heard that REDengine has anything to do with Aurora engine. I think they started making W2 with it, while at the same time they were developing their own engine, but they ran into trouble with the game and it was delayed and they decided to switch engines. You can see that the leaked "W2 internal video" still looks very much like the W1, and was clearly using the same engine, while the final product looks and plays entirely different.
