Voted a 4. I played though this game 3 times to get my 20th platinum, once to enjoy, twice for the hard difficulty and thrice to not use hysteria (yes, I know could have short cut it, but I like the game
)
Hard was very difficult for me until I gave up and bought the DLC which made it. Piece of cake with the double power weapons dress lol without the DLC I would have probably rated the difficulty a lot higher.
Getting neigh slayer was a pain in the ass, and I got it from some advice on here (radula room 2 in chapter 2).
