Achievements for an Xbox 360 version of Resident Evil: Revelations have appeared online, before Capcom has even confirmed the game’s existence.
Back in November last year the Korean Ratings Board put up a listing for the title on Xbox 360 and PlayStation 3. Now Exophase has posted up an Achievement list for the game on Xbox 360.
Capcom is still yet to announce that the 3DS game is actually being ported to Xbox 360 and PlayStation 3, but I think that a ratings listing and Achievement list is a pretty good indication that it is. I’m interested to see how a 3DS game will translate onto consoles.
