Finished with the game. Never got all the unlockables as one playthrough was enough, but damn was it fantastic. Incredible game, incredible story. My second favourite of the series after MGS5.
This game is TURBO shit. You can't see where the fuck you're going because of the FUNNY jpeg environments. I'm sure the story is good but the game is nigh unplayable because of the fact you don't know wtf you're doing and the save points are cringe. Aged like milk.
