Stop sorting by 1 star reviews! Every single one of them is complaining about its difficulty, and not saying any objective or constructive arguments.
The dlc, while very difficult, is a masterpiece. The sheer amount of content in here is astounding. I have played it for 12 plus hours just exploring, and i have only beaten 1 of the main bosses.
The art direction is absolutely gorgeous. The level design and connectivity is unprecedented, i have never in my life seen any game put such massive, diverse and interconnected zones in a relatively “small” map like this one, thanks to its verticality.
Yes, the main bosses are extremely challenging, and if that is not your cup of tea, you can always hop on multiplayer, summon a friend or any of the NPC summons. Every main boss has an NPC summon if you find them too challenging.
In my opinion, this is the best fromsoft dlc i have ever played.
