Fortnite, developed by Epic Games, introduced the concept of battle passes in its mobile version. The battle pass system was revolutionary in its approach, offering players a way to unlock cosmetics and other in-game rewards by playing and leveling up. Unlike traditional DLC models, battle passes keep the game monetized without dividing the player base, as all players can access the same content. Fortnite's battle pass offers various tiers of rewards, with players unlocking these tiers by completing challenges and playing regularly. This has kept players engaged with Fortnite over long periods, as there are always new items to unlock with each season.

Fortnite's battle pass system became a blueprint for other mobile games looking to keep their players engaged. By offering exclusive, time-limited rewards in exchange for completing in-game objectives, players feel incentivized to stay active and committed to the game. The battle pass system also offers a free version and a paid version, providing non-paying players with rewards while encouraging paid players to invest more. This system has since been implemented in many other mobile games, including PUBG Mobile, Call of Duty: Mobile, and more, marking a shift in how mobile games are monetized.
