Fortnite, developed by Epic Games, introduced the concept of the battle pass to mobile gaming, revolutionizing how players unlock content. The battle pass allows players to unlock cosmetic rewards by completing challenges and leveling up over the course of a season. The paid tier of the battle pass provides access to exclusive skins, emotes, and other items, while a free version offers a limited set of rewards. This system keeps players engaged throughout the season, encouraging them to play regularly to earn all available rewards.

The success of Fortnite’s battle pass has inspired many other mobile games to adopt similar models, including Call of Duty: Mobile and PUBG Mobile. The system provides a steady stream of revenue for developers without fragmenting the player base, as all players, regardless of purchase, can access the same content. Fortnite's battle pass also introduces new content each season, maintaining excitement and giving players a reason to return to the game. This model has become a cornerstone of monetization in mobile gaming, offering a balance between player engagement and profitability.
