Alternative for side loading apps on player... topic

I'm not sure if this is been discovered, but I figured I'd post is here.
I just downloaded modern combat 5 on my Nexus player through the Google Play Store.
I had to do it through the actual player using the voice search function, but it allowed me to purchase it. DL-ing as we speak.
