Fortnite Battle Royale is a free-to-play battle royale game developed and published by Epic Games. It was released as an early access title for Microsoft Windows, macOS, PlayStation 4 and Xbox One in September 2017, for iOS in April 2018, and the Nintendo Switch in June 2018, with plans for an Android version in Q2 or Q3 2018. It is a spin-off from Epic's Fortnite, a cooperative survival game with construction elements (often referred to as its "Save the World" mode). As a battle royale game, Fortnite Battle Royale features up to 100 players, alone, in duos, or in squads of up to four players, attempting to be the last player alive by killing other players or evading them, while staying within a constantly shrinking safe zone to prevent taking lethal damage from being outside it. Players must scavenge for weapons and armor to gain the upper hand on their opponents. The game adds the construction element from Fortnite; players can break down most objects in the game world to gain resources they can use to build fortifications as part of their strategy. The game features limited cross-platform play between the PlayStation 4, Xbox One, Nintendo Switch, personal computer, and mobile versions.

The idea for Fortnite Battle Royale came near the release of Fortnite in mid-2017. Following the early access release of PlayerUnknown's Battlegrounds in March 2017 and its rapid growth, Epic Games saw the opportunity to create a battle royale mode out of Fortnite. Originally released as part of the paid Fortnite game, Epic spun out a dedicated version of the game offered as free-to-play funded by microtransactions, sharing in-game currency with the main Fortnite game. The game is free-to-play, supported by microtransactions that allow players to buy "Vinderbucks", the game's internal currency. V-Bucks are also shared with the main Fortnite "Save the World" game, which offers players the opportunity to earn V-Bucks by completing missions or daily quests. V-Bucks can then be used to buy cosmetic improvements to the player (heroes, character and weapon skins, and emotes). V-Bucks can also be used to buy Battle Passes and have access to do seasons weekly missions which accelerate the rate that a player increases their Tier within the game's "seasons" (each season lasting a few months). By raising their tier, they gain automatic rewards of cosmetic items typically around a theme. Players can still increase tiers without a Battle Pass, albeit at a slower rate.
