During today's Sonic Central stream to celebrate the anniversary of the Sonic the Hedgehog franchise, Sonic Team announced that the second free content update on Sonic Frontiers' 2023 roadmap, titled Sonic's Birthday Bash, is available today. The update was announced in November 2022 as part of the game's 2023 roadmap.

The Sonic's Birthday Bash update adds new challenges, moves, and a new kind of collectible Koco for Sonic. The update also promises free birthday decorations for our hero, as well as the addition of New Game Plus. As is standard with most New Game Plus modes, you can begin the adventure from the start with all of your skill tree and power-up levels carried over into the new file.

Sonic's Birthday Bash arrives free to download beginning today at 5 p.m. PT / 8 p.m. ET. The first of three content updates arrived in March, adding a photo mode, Cyber Space Challenges, and Battle Rush mode, plus a jukebox featuring collectible songs from Sonic's past. The third update, which promises to be the most substantial, adds new playable characters and a new story and is set to arrive later this year.
