After months of waiting, Epic has finally released a mobile version of the Epic Games Store, which is now available for Android devices worldwide as well as EU iOS devices.
Honestly I know people here are against Epic, but Google Play is such garbage that I welcome the epic store on Android.
I wouldn't be surprised if they had a launcher before and they're releasing a "Store" now that Google and Apple have been slapped with anti-trust lawsuits. I think your best bet would be asking the folks at the Epic forums.
