Pokémon Go dataminer indicates a Battle Pass may be coming to the game

A notorious data mining group, known as PokeMiners on Twitter, discovered a new item in Pokémon Go’s file called the “Battle Pass Ticket.” The ticket was discovered as part of the game around August 3, and the dataminers didn’t specify what the item entails. Since it’s a ticket, the Battle Pass Ticket will most likely give players access to an upcoming event where they can gain items. Niantic has released ticketed events beforehand in Pokémon Go, sometimes bringing new exclusive cosmetics for players to collect.

The Battle Pass Ticket was probably included in the game during the latest update and will likely be available to purchase on a date not so far off. Expect to hear something official about it soon from Niantic, but currently, the Battle Pass Ticket can only be uncovered through data mining and will not give you access to anything yet. Ticketed events like Battle Passes generally cost real-world money to buy, so expect to see the new Battle Pass Ticket show up in the game’s store.

Sometimes, special events like Battle Pass are when players can gain exclusive items like outfits, poses, and Pokémon costumes. However, other times Niantic will reward participating event goers with a surplus of common items that players can gain through normal gameplay, like extra poffins, incense, Pokéballs, and Poké Coins. We can only wait and see what the new Battle Pass will have, yet based on the comments on PokeMiners Tweet, fans are not optimistic about the chances of the Battle Pass including exclusive items.
