Grounded gets Verified on Steam Deck with the Release of the Super Duper 1.2 update
The Grounded 1.2 update has landed, with an extra perk, it's now Verified on Steam Deck
On top of that, there is a 25% discount until May 4 (insert joke here)
The biggest issue that prevented Grounded from being verified before was the login issue with Microsoft Xbox, this is now working with a dedicated Keyboard button and controller navigation support.
