Sony has announced that PlayStation 5 exclusive Astro Bot is receiving a free expansion tomorrow, December 12th, adding a whole new level called Winter Wonder to the popular platformer.

In a PlayStation blog post, it was announced that the expansion will launch at 6pm Pacific Time or 9pm Eastern Time, which is 2am on December 13th in the UK. It is available to all Astro Bot owners at no additional cost, but requires completion of the base game to play.

“Since releasing Astro Bot on PlayStation 5 earlier this year, we have been overwhelmed by the kind comments from you and the PlayStation community and are pleased with the critical response to the game around the world,” said Nicolas Doucet, Studio Director of DevTeam Asobi.

“We would like to thank you from the bottom of our hearts for your appreciation. It really means a lot to us. To say thank you, it’s my pleasure to announce that a whole new piece of free additional content is coming to Astro Bot. In fact, the little robot elves from Team Asobi have been very busy creating a whole new level called Winter Wonder to prepare.

Doucet didn’t reveal much about what fans can expect from the new level, although a single screenshot shows a festive world with a large Christmas tree in the center.

“As we want it to remain a bit of a surprise, we won’t say too much, but you should expect a fun level with shiny gifts, a good helping of Jingle Bells, and brand new special bots to add to your crew,” Doucet said .

“This winter update is designed for every user, meaning it’s a celebration that’s fun for kids and adults alike. So this time, not a hair-raising challenge,” he added, likely referring to the previous series of speedrun challenges released as downloadable content.

Astro Bot sold 1.5 million units in its first two months of sales and received a 9/10 in IGN’s review. “Astro Bot is a fantastically inventive platformer in its own right and something very special for anyone who cares about the PlayStation,” we said.
