I'm still playing Horizon Zero Dawn. It includes the Frozen Wilds DLC, which I finished today, or at least its main line. There's a ridiculous difficulty spike in several combats at the end that almost made me give up on the game - more combats against very difficult and sponge machines in a tight area. I simply switched to story mode and resumes normally after that part (unfortunately, it wasn't possible to leave the area and get back later, or even to reload before the whole thing).
I don't know what went through their heads when they designed that part. I hated it. After that, I watched FightinCowboy and he apparently had troubles in the last combat, too, which he didn't like either (

And of course, no way to refill health potions during most of the quest, so I almost ran out.
