Firework Season brings tons of new content to, and one piece of that content includes free three- and four-star outfits for every player, regardless of quest progress or whether they're free-to-play.
According to Infold, the next two upcoming updates will include free outfits as well, bringing the total gifted to players up to nine.
Once your game has been updated to the new 1.2 patch, you can hop in and claim these outfits. Balancing the free-to-play and paid experiences of gacha games can be tricky, as most gacha games are free-to-play by nature.
With the game being free, studios have to recoup production costs somehow, and incentivizing spending money on in-game items, power-ups, and in 's case, clothes accomplishes just that.
This being said, free gifts can go a long way in building goodwill with the community and keeping players invested, and Infold is taking that approach in this patch.
