It will be one Mikołaj Stroiński, the same man who (along with currently working on Cyberpunk 2077 Marcin Przybyłowicz) has created the soundtrack for Witcher 3. The man does not have to be advertised to anyone who played W3 – if you do not remember, check out the game’s opening theme. Good? Good.
Sadly, there is nothing new that we know about the game itself. It is being made by Relic Entertainment, veterans of the RTS genre, which is good. Its release date is unknown. What we do have is a teaser trailer that is definitely worth looking at.
