An M-rating is the second highest rating the ESRB offers to media, with only an "Adults Only" rating being higher, although this is a very rare rating for products. An M-rating means the product is suitable for anybody aged 17 and up, and based on the story details revealed in the rating description, it's easy to see why Resi 7 is for mature audiences only.
According to the ESRB, players will take control of 'Ethan' in Resident Evil 7 as he ventures through a derelict mansion in search of his missing wife.
Note that the below description will include minor spoilers about the contents of the game!
The game is in first person, of course, as it has been built to support PlayStation VR, and will include pistols, shotguns flamethrowers and explosives to help the player kill "mutant creatures".
The phrasing of "mutant creatures" is interesting. We're pretty sure the ESRB would comfortably define a zombie as such, so perhaps we'll be facing a very different threat in this mansion.
"As players progress through the story, cutscenes can depict instances of gore and intense acts of violence," the description continues, "a character's arm dismembered by a chainsaw; a man's leg taken off at the knee with a shovel; a character impaled through the face with a shovel. Some areas also depict mutilated corpses with exposed organs/viscera."
Oh and also the use of the f-word and s-word is mentioned, so it'll be a joy for the ears as well as the eyes.
Having played Resident Evil 7 in VR at E3 this year, I can't wait to check out the full game. I'm sure anybody who's played The Beginning Hour demo will also be equally excited.
