Epic Games bypasses the app store to offer its hugely successful online shooting game via its website

Online shooting game Fortnite: Battle Royale will be available on Android phones this month, but it will not be available on the Google Play store, the official app store for Android devices. Instead, developer Epic Games will make the game available for download via a dedicated installer on its website, avoiding the 30% revenue share that Google would get to host the title on its Play store.
