PUBG Corp has filed a lawsuit against Epic Games for copyright violation, according to a Korea Times report. The Korea-based PUBG Corp filed the injunction against Epic Games Korea in January, alleging copyright infringement. The Seoul Central District Court will decide whether Fortnite copied PUBG, though no further details concerning the claims have been revealed.
Epic Games released Fortnite's free-to-play Battle Royale mode in September last year, after the game's vanilla PvE 'Free The World' mode struggled to gain traction. PUBG publisher Bluehole weighed in on the similarities between the modes in September.
