“Batman: Return to Arkham” Rated by PEGI
Without "Origins"
According to a PEGI listing, it adds more credence that the HD collection "Batman: Return to Arkham" exists.
This collection is supposedly the first two games in the series: "Batman Arkham Asylum & City." "Origins" seems to be left out due to developer Rocksteady not working on the game. There seems to also be a pre-order date of April 19 (that's today as of this writing), whereas the collection doesn't hit until later this summer reportedly in June.
