Select an unlocked (yellow) Sector on the Battle Pass map to see the Sector's rewards.
Tap Inspect to zoom in on the Sector's rewards.
Highlight a reward and select Claim Reward.
Note: Whether you have the base or premium Battle Pass, rewards marked Free are available to all players and must be claimed with a Battle Token Tier Skip.
You will need to claim the four base rewards before you can claim the High-Value Target (HVT) reward.
Players with the base Battle Pass need to claim all five rewards in a Sector to unlock new Sectors but will only receive the reward marked Free. When upgrading to the premium Battle Pass, all rewards that have been claimed will be available to use.
