Epic has shared a few more details about the upcoming Android release of Fortnite. After launching on iOS back in April, the phenomenally popular battle royale game is coming to Android devices this summer, and the developer has now revealed that the game won't be available through the Google Play store like most other games for the platform. That allows Epic to make more money on each purchase in the free-to-play game, but it means that users will have to go through a somewhat unconventional process to download and install it.

Epic confirmed to GameSpot that Android users will not be able to download Fortnite on their devices from Google's digital store, but rather through its own service. According to the developer, this decision was made in part to bypass the 30% "store tax" that would normally be applied to purchases made on Google Play.
