Fortnite is a free-to-play battle royale game created by Epic Games. It features an island in which 100 players fight to the death using items they have found on the island. Since its launch, Fortnite has accumulated more than 350 million registered users as of 2021. The popularity of Fortnite rose even more with collaborative online concerts done with artists like Travis Scott and Ariana Grande. With gradual updates, Fortnite has become a complex IP rather than a simple battle royale game.
