Using the code to unlock MAD CHAINSAW MODE on the RE4 Demo (PS4)
Been meaning to upload this for a few days...but better late then never!
To Unlock Extreme Difficulty "Mad Chainsaw" Mode:
Highlight Main Story and Hold L1 + R1 and press Up, Left, Down, Right, Square Triangle, Circle, X, X...then PRESTO! An image of the chainsaw man should pop up if you entered it successfully. Good Luck fellow RE fans!
