From Polygon: “Nier Replicant ver.1.22474487139 doesnt have fast travel, but there is a side quest early on Boar Hunt! that earns you a wild boar mount. Its pretty challenging, but being able to zip around much faster makes it worth it.
In this Nier Replicant remake guide, well walk you through the Boar Hunt! quest, including where to pick up the quest, where to go to find the wild boar, how to defeat it, and how to use your new mount.”
