This is my Akumu Difficulty professional No Upgrades and No Keys Walkthrough for The Evil Within PC Steam version. Basically I will try to play through the game on its hardest difficulty setting, avoiding any skill upgrades or using any locker room keys. I will however try to collect all available collectibles in the game as well as pick up all the keys in each chapter. This is a very hard challenge and I only recommend it for experienced players as you will have to know the game in an out. On Akumu difficulty Sebastian will die in one hit and there are more enemies, with more health and on top of that they are faster.
