Premium users can utilize a ‘Tier Hack’ feature to swap a seasonal Legendary skin for an item from a curated ‘Swap Pool’ of legacy cosmetics. Furthermore, a mid-season ‘Unvaulted Pass’ has been introduced to help players catch up on previous seasonal rewards. Additional content includes the ‘Shooting Star: My MEKA Mania’ event, running through August 31, which allows players to vote for their favorite MEKA Squad members.
