The rating comes hot on the heels of Bethesda announcing Shinji Mikami's The Evil Within, so it could be another codename for the horror game; The Evil Within isn't listed on the Australian Classification Board. Or it could be something else entirely - a surprisingly gritty adaptation of the 1974 album by pop sensations The Beach Boys, maybe. We asked Bethesda, but a company representative told us he couldn't comment on the listing.
A surfer-slasher re-imagining it is, then.
Update: A Bethesda representative has reached out to say, "We have nothing to share at this point." And we're back to surfer-slasher.
