Now, PUBG developer Bluehole has issued a response to what it describes as “growing concerns” about the similarities between the two games. “We’ve had an ongoing relationship with Epic Games throughout PUBG’s development as they are the creators of [Unreal Engine 4], the engine we licensed for the game,” Chang Han Kim, Bluehole’s vice president, said in a statement. “After listening to the growing feedback from our community and reviewing the gameplay for ourselves, we are concerned that Fortnite may be replicating the experience for which PUBG is known.”
