From the beginning, all players have immediate access to Battle Pass, the free rewards stream in the Call of Duty: Mobile content delivery system.
Through normal public gameplay or by completing daily and weekly Tasks, you’ll earn experience towards increasing your Tier and unlocking rewards within the 50 free Tiers in the Battle Pass rewards stream.
Rewards include free Weapon XP Cards, Credits, Character Skins, Weapon Skins, and more. Rank up to Tier 100, and you’ll earn the rare Type 25 - Pinstripes assault rifle.
Note that not every tier in Battle Pass comes with a reward.
