PlayerUnknown’s Battlegrounds publisher PUBG Corporation is no longer suing Epic Games over Fortnite.

PlayerUnknown's Battlegrounds, or PUBG, is a popular battle royale-style shooter game that spawned countless imitators. In January, PUBG Corporation filed a lawsuit in Korea alleging that the maker of free-to-play competitor Fortnite ripped off PlayerUnknown's Battlegrounds. Although its concept is similar to PUBG, Fortnite is wildly popular in its own right. "We filed the suit to protect our copyright in January, " an unnamed PUBG Corporation official told The Korea Times at the time.
