Metroidvania is anything but a dead genre, but this "resurrection" might be a bit on the nose. The Mummy Demastered combines the ancient evil entities of Castlevania with a more modern arsenal of Metroid into one game carrying the IP of a dead "franchise" trying to gain relevancy again.
It's a bit much.
Also, who cares, I'll play it! (Especially after WayForward's excellent Aliens: Infestation).
