Fortnite has eclipsed the once dominant PlayerUnknown’s Battlegrounds title, both in terms of mindshare and money. Last week, the former was reported to have pulled in $296 million for the month of April — a financial windfall that’s only likely to increase as the title makes its way to Android in the coming months.

Now the company behind PUBG is taking Fortnite’s creators to court. PUBG (the company), a subsidiary of Bluehole (the company behind PUBG, the game — slightly confusing, I know), has filed a suit against Epic Games over copyright infringement concerns. The South Korean suit, noted by The Korea Times, takes particular issue with Fortnite’s battle royale mode.
