It seems highly likely that a Castlevania announcement is imminent, thanks to two rating board posts in quick succession in the last week. Castlevania Requiem: Symphony of the Night & Rondo of Blood appears to be a bundle of two classic entries in the series. Symphony of the Night is available as a PSOne Classic, but Xbox has had an achievement-listed version for many years.
While the news first broke on the Korean ratings board, the Entertainment Software Ratings Board post gives us a rating description for the bundle, which we have to assume is a PS4 exclusive for the time being. Certainly, from the descriptions of the way the game handles violence and nudity, it sounds like an intact version of the PC Engine and PlayStation originals.
This is collection of two action platformers in which players assume the role of a vampire hunter battling Dracula and other creatures. From a side-scrolling perspective, players traverse Dracula's castle to kill fantastical enemies (e.g., zombies, demons, minotaurs). Characters use whips, swords, axes, and magic to defeat enemies. Pixelated blood is depicted when players' character and creatures are killed; some attacks result in decapitation and dismemberment of creatures, including a boss character that loses its body parts and entrails. As players progress, they may encounter female creatures (e.g., harpies, medusa) that have exposed buttocks and are depicted topless, though there are no discernible details (i.e., no nipples).We'll share more details once an official announcement is revealed.
