since it was ported to PC, there could be a PS/MS version of this in a year or two and would fix those issues and would receive high scores like ZombiU. :D
Several posters in NintendoEverything mentioned that Edge is really hard on those new IPs or so, and Until Dawn got 7 which would translate to 8.
I like hack n slash then add those guns, I'm good with it but not a day 1 buy for me.
