Here’s the Twitter thread discussing this
Basically, some different apps were linked to the official steamVR app. These apps are hidden, but the data miner was able to grab some assets from them that included some custom art for Waydroid, which is a Linux program that lets you run Android apps on Linux.
Additionally, I’ve seen comments saying that some valve devs have been making pull requests for the Waydroid github, but I don’t actually have a proper source for that.
I can’t imagine wanting to play a mobile game on Steam Deck… but having access to other native apps sure sounds like a win. Didn’t consider that.
