There's no official date as of yet, but one anonymous leaker who claims to have a Respawn-connected roommate told DailyESports it would drop on Tuesday, Mar. 12. There's no way to verify his claims, but it would benefit Respawn to launch the Battle Pass sooner rather than later.

The way Respawn describes the Battle Pass on the Apex Legends site lays it out: "Compete every season to unlock new Legends, fresh weapons, themed loot and more."
