After making your way through the first two main areas in Forbidden Horizon in the West, you’ll get to the point where Aloy meets the new version of GAIA she’s building. This is when you will establish a base of operations from which to come out and assemble the AI subordinates. However, after meeting GAIA, there is an important choice: should you go West or turn East? This guide explains what each option means.
Choose one and come back to the other later
In the end, this choice does not have great consequences. The only impact it has is your time in the game right after leaving the facility. If you choose to go West, you will continue the story and enter a new area of the Forbidden West. Aloy will earn some experience and unlock three new main quests for each AI subordinate. From there, you can choose which mission to follow or explore the West at your leisure.
If you choose to go back east, you will be able to complete all the side quests, contracts, and activities you left behind in the previous area. However, if you want to clear things up in the area before moving forward, you should head back east before venturing further west and continuing the story.
