Bloodstained will be released on all eighth generation consoles including Microsoft Windows and OS X. The story follows protagonist, Miriam, who is an orphan afflicted an alchemist's curse which is turning her skin crystal. In order to rid the curse, Miriam must explore a demon-filled castle and find Gebel, the summoner. Gebel has suffered from the curse for a very long time. The game will have what we would call a "Metroidvania" style gameplay. You will go around defeating enemies which will gain your character, Miriam's power enabled by the crystal on her body as well as items that can be used to craft new weapons and armor.
The game will have a 2.5D style gameplay meaning it will have 3 dimensional graphics still have the 2-D sidescrolling movement. The idea of using a 2.5D style will make it almost a continuation of the Castlevania series.
So, will we see a Wii U release for the epic upcoming 2.5D platforming, "Metroidvania" sequel known as Bloodstained: Ritual of the Night? I sure hope so! (I think it will happen.)
