Two video-game giants are about to face each other in court.
PUBG Corp. is suing the Korean division of Epic Games, which is the developer of Fortnite.
PUBG is claiming that Fortnite copied its game, PlayerUnknown's Battlegrounds.
Both games have 100 players who battle it out to be No. 1. However, this isn't unusual for a multiplayer video game. What is unusual is that PlayerUnknown's Battlegrounds uses Epic Games' Unreal Engine technology. The software helps developers build games and is considered the industry-standard.
PUBG is officially suing for copyright infringement. The suit was filed in South Korea.
PUBG responded to Bloomberg, "This is a measure to protect our copyrights."
"We don't comment on ongoing litigation," a spokesperson for Epic Games said in an email.
