An August 29, 2021 PUBG Mobile Indonesia presentation confirmed that Jujutsu Kaisen is coming to the battle royale. The brief announcement only showed a promotional image with what appeared to be cursed energy and a curse over the battle royale’s familiar island while the series’ Lone Survivor looks on.
Here’s the brief announcement. It comes up exactly at the 16 minute mark of the PUBG Mobile 2021 Team Up Challenge – Pertandingan Final video. The announcement doesn’t mention how the crossover will exactly work. It is possible there will be cosmetic items resembling characters from the series. There could also be changes to the environment that could contain different elements from the anime and manga series.
As for a dedicated Jujutsu Kaisen game, one is on the way. Sumzap is working on Jujutsu Kaisen Phantom Parade. That will be a mobile RPG.
There’s also a Jujutsu Kaisen Tamagotchi in the works. That will show up sometime in December 2021. When it launches, it will let you raise characters from the series.
PUBG Mobile is available on Android and Apple iOS devices, and the Jujutsu Kaisen event doesn’t have a release date yet. The Jujutsu Kaisen anime is available to watch on Funimation. Viz Media is handling the English release of the manga.
