Epic Games released Fortnite Battle Royale on September 26, 2017, as a free-to-play mode branching from the original cooperative Fortnite: Save the World. The game dropped 100 players onto an island to compete until one remained, combining shooting mechanics with a building system using harvested materials. Within months it reached 125 million players across PC, console, and mobile platforms. Its revenue model relied on cosmetic microtransactions and a seasonal battle pass system rather than pay-to-win mechanics.
