Only Star Passes purchased with Robux are tradable. Star passes summoned from the banner before 7/1/22, however, are still tradable.
Overview[]
The Star Pass is a progression system that was added as a part of Update 27. There are multiple tiers which give certain rewards for each tier such as Units, XP, Coins, Gems, and Capsules. There are two tracks: a free one and Star Pass Ultra, which offers additional rewards on top of the free track. The Star Pass Ultra track can be unlocked by using a Star Pass Ultra unit, which can be obtained via Banner Z in World 2 as a 6-Star, evolving 1 Mysterious Key and 20 Current Capsules, trading, or by purchasing it for 799 Robux.
You can get star pass experience by either completing missions, story mode levels, raids or reaching certain wave in infinite mode, completing this tasks on extreme mode will NOT give extra pass experience.
