Far Cry Primal used the same map layout as Far Cry 4, right down to the very same river crossings.
The changes were spotted by Gamespressure, and you can see them below. As you can tell, many of the islands and even roads are in the exact same location. Of course, since there were no bridges in Far Cry Primal, they are replaced by other crossings but still in the same spot. Take a look below and let us know what you think.
We've reached out to Ubisoft for comment, but we're assuming it was done due to the short turn around time between the two games in order to speed up release.
