Just in case it's flown under anyone's radar and they're interested in such things.



Valve has released a beta version of their Steam Link app for Android lollipop and above, iOS at a later date.



I've read people are having limited success with controllers other than the Steam one so far, I'll be giving my Mad Catz CTRLR a try with it tonight.
