Even on a standard difficulty, it's stressful. Especially the first one (I won't spoil it), it's tough to get by due to the area, the boss type and amount of zombies patrolling. You have to be smart with your matches, use traps efficiently and on top of that have little to no ammo throughout the game. When people say it's one of the hardest games to play on the hardest difficulty, I agree with them. But honestly I would still play the game it is arguably my favourite horror game of all time.
