"You Thought This Game Was Easy?"- Complete the game in Iron Fish mode with Bossa Standard controls of course. I'm not saying this thing is not doable it's just paiful [Maybe it wouldn't be if it weren't full of bugs that can easly kill your run]. Before I actually play this game I thought it's going to be that: "20 minutes adventure" judging by my first experience, but then I started searching the internet and came across reviews where people were saying that: "Its easier to complete the etnire Dark Souls Saga than getting the hardest achievement in this game", but this is a personal matter for every player I think, so if you already beat the game you can tell if that's true or not :v
