Due to similarity concerns, PlayerUnknown’s Battlegrounds, or PUBG, has filed a lawsuit against Fortnite developer Epic Games for copyright infringement, The Korea Times reports. The documents were submitted in Korea back in January, as the Seoul Central District Court will in turn be forced to determine whether or not Epic Games and Fortnite have borrowed directly from PUBG.

Following last year's success of PUBG and its battle royale mayhem, Fortnite and its comparable multi-person shooter mode have soared in popularity, as the game made nearly $300 million USD last month alone. More recently, Epic has announced a $100 million USD Esports tournament prize pool.
