Sanhok is perhaps PUBG: Battlegrounds' most controversial map. The map was introduced in 2018 as PUBG's first 4x4-sized map, the smallest the game had at the time. The map was criticized for its low visibility and dense foliage, but it was also the most played PUBG map for some time after its release. Sanhok has since gone through a massive overhaul, which has only made the map all the more controversial. Perhaps in response to negative feedback, Krafton is now going to re-release Sanhok with many of those changes reverted.
