ESRB has rated Catherine for PC confirming the earlier rumors that the game is indeed coming to that platform.
Atlus was teasing a Catherine port for PC through an ambiguous message that was posted on the Bayonetta Steam discussion forums. The message was simply “Baaaaa” which fans quickly linked to the iconic sheep design in Catherine. Soon, it was discovered that ESRB had rated the game on PC as the rating was updated to reflect the addition of a PC version.
There is a new version of Catherine titled as ‘Full Body’ with additional content that will release for the PS4 and PS Vita. Catherine Full Body is not the version rated by ESRB, rather it is the original game without any of the new content. It is also available on the PS3 and Xbox 360. The game is already rated for the Xbox One in addition to PC since it can be played through backward compatibility.
Atlus hasn’t formally made any announcement but after the update to ESRB rating, it is pretty much certain that Catherine is coming to PC. It is just a matter of waiting for them to make an announcement for it. It doesn’t look likely that the new version with additional content is making its way to any other platform aside from PS Vita and PS4.
