I agree, the first boss is the hardest one imho - it is a skill check of sorts. After I beat them it really clicked with me and I more or less blasted to the game in one go. It is truly a masterpiece, I couldn’t have described it better!
I played the first one when it came out… so I hardly remember anything anymore haha. But remember using two different bow and slingshots as well as the weapons for tethering the machines…
Could be that I wasn’t in the right mindset when I played it, but for me it felt like more of the same. Since Zelda BOTW I also find it a bit awkward when you are not able to climb everything - but this is not solely in Horizon the case. It certainly was a gorgeous looking game with a fantastic story and world, but the gameplay never really clicked with me… and I really can’t say why exactly, probably a combination of a few things. I never got into Monster Hunter, maybe that’s also a factor.
You are welcome! I was really confused when the DLCs were mentioned in the PSN description, but I couldn’t find them… And definitely play them - I don’t want to spoil anything haha, just do it!
