Players of Zenless Zone Zero can claim up to 2,000 free Polychromes using specific redeem codes and anniversary gifts. The game recently detailed its upcoming update, Version 2.1, which will introduce new characters and various events.

HoYoverse’s popular action RPG, Zenless Zone Zero, is nearing the completion of Version 2.0, the largest update so far. This patch not only marks the start of the second season of the main narrative but also celebrates the game’s first anniversary, where players received an S-Rank character of their choice and a significant amount of free pulls. With the launch of Version 2.1 on July 16, even more rewards are being offered, but only for a limited time.

Beginning July 4, 2025, players can claim 2,000 free Polychromes, along with other resources, to thank them for their support over the past year. The first redeem code from Zenless Zone Zero’s latest special program grants 300 Polychromes. Additionally, five special codes on social media provide 20 Polychromes each. To celebrate the anniversary, all players will also receive 1,600 Polychromes through their in-game mail, totaling 2,000 Polychromes, which equals 12 free pulls. Keep in mind that the redeem codes will expire, and there’s a specific period to claim the in-game rewards.
