Fortnite’s journey to Android has been a complicated one. A few months back, Epic Games promised to bring the wildly popular survival sandbox title to the mobile OS, but only after side stepping the traditional process for doing so. Fittingly, while it now appears to be live for Android, the process of actually getting the game is, well, complicated.

If you want to get started, you’ll need to sign up for a beta of the game. That’s right, while the title has been up and running on any number of other platforms (including its three-day head start on Samsung devices), it’s still in beta on Android. Give Epic your email address, and they’ll send you an invite…”as soon as you can play.”
