The “Battle Royale” to be the king of the Battle Royale mode in the video games industry just took another road, a road that will leads to a courthouse. The recently dethroned King of Battle Role, PlayerUnknown’s Battlegrounds (PUBG), has its developers suing Epic Games for copyright infringement with its Fornite Battle Royale, which for now, wears the Battle Royale crown in terms of concurrent players.

In a news report by The Korea Times, PUBG has filed an injunction with the Seoul Central District Court against Epic Games Korea. It alleges that Epic Games copied “Battlegrounds" items and user interface (UI). Fortnite did not start out as Battle Royale video game, compared to PUBG which is Battle Royale game since its inception as a Steam early access beta program in March 2017. Fornite introduced its own Battle Royale mode in September 2017.

Bluehole, which owns the PUBG subsidiary, has been said to be planning in September 2017 to respond to the claims of similarities between PUBG and Fortnite Battle Royale.

Whilst there are similarities between the games, there are also differences such as graphics and that Fortnite allows you to construct walls based on its “Save the World” game concept which it is what it started with. With PUBG, it is just straightforward compact, where players get to pick weapons to use in the game and an ever shrinking safe zone, which are two features in the Fortnite Battle Royale Mode.

Over 40 million copies of PUBG have been sold but Fortnite holds the concurrent player numbers at 3.4 million versus 3.3 million for PUBG in February 2018 as reported by Engadget.

PUBG uses the Unreal Engine which is owned by Epic Games, which will make their technical relationship uncomfortable. Also, the Battle Royale mode is a not a unique concept that started with PUBG, H1Z1 is a Battle Royale mode video game from the Daybreak Game Company which started its life as an early access title in January 2015, just like how PUBG started its life.
