If you picked up lords of the fallen and expected it to play anything remotely like dark souls than yer a dope.
Think of lords of the fallen as "clunky souls."
Heavy armour is your friend, everything is heavy for you and your actions are less agile and more grounded in real physical combat than dark souls.
So. Is it harder than dark souls? Eh. Maybe. That depends on what happens when you start to really learn the ropes.
