Are you finding it difficult because it's just a difficult game or are you finding it difficult because certain mechanics of enemies are designed with primary focus on MP?I'm finding it kind of difficult but I'm enjoying the gameplay loop.
Its unsettling to play alone for me lol, it's like RE where you can hear enemies growling and walking around long before you see them so you're on alert most of the time.
I wish there was more loot but it's not that kind of game.
I've been following impressions, and one discussed a boss fight where a friend focused on adds while the other focused on keeping the boss's attention. It sounded deeply frustrating if not balanced right.
