The new update includes:
- Full cross-platform gaming and account linking across mobile devices and Nintendo Switch. Link an account and play with the same account on both platforms.
- New in-game events where you can get super item upgrades that can upgrade a held item to rank 30. We’ve also made it easier for all Trainers to get item upgrades.
- New items retained to introduce new strategies.
- The introduction of Unite Squads, which allows coaches to team up with squad mates.
- A second battle pass, which will feature all-new cosmetic elements, including the new Holowear with special visual effects.
- The release of some limited spectator mode features.
- Support for multiple new languages.
The new Battle Pass has a space theme and the main reward is a new ‘Galatic Ghost 094’ skin for Gengar and much more.
It also looks like Sylveon and Mamoswine will be coming with the update as well.
