Aloy’s struggles can easily be mistaken for an adventure. Although, for you the gamer, it’s an adventure like no other. There’s not a lot of tension and drama here. Even though Forbidden West tries to sell you that the world is ending, people are fighting and politics is omnipresent. It always surrounds you with the people that want your best interests, and you’re constantly fighting pre-established enemies, be it machines or humans.
Be that as it may, there’s a new threat that is destroying Earth. It is slowly chewing into the natural resources because some AI is being mischievous or maybe the AI that is supposed to fix everything is half-baked at best, we don’t know but Aloy must travel to the Forbidden West and grab the remaining AIs that are responsible for creating a balance and merge them with the central super intelligent and weirdly empathic AI known as Gaia.
The story also picks up a few months after the first game so you might want to finish Horizon Zero Dawn first before jumping into Forbidden West. The game also has old characters making a return along with many new ones. If you don’t want to play the older game, just look up a video on YouTube to catch up to the story before you play Forbidden West – it's not a deal-breaker.
