Epic Games’ smash hit multiplayer video game Fortnite was recently released on mobile Android devices after previously only being available on Samsung phones.

Until recently, Fortnite was only available for play via traditional consoles. The game has experienced massive success both in the U.S. and abroad. It is based around a simple premise: you and other players work to build a fort and defend it from a variety of monsters.

Due to popular demand, Epic Games announced that they would release a mobile version of the shooter for smartphones. Initially, Fortnite Mobile was offered to all Apple IOS users and Samsung Android customers. The exclusivity of the Samsung release was planned to promote the newest Samsung phone, the Galaxy 9.

There was significant backlash from Android users who didn’t happen to own a Samsung phone. This week, Epic Games released Fortnite Mobile to all Android users. However, gaining access to this version of the game first requires an invite to the beta testing version.

The move came in response to criticism from gamers, but the expansion also represents a massive increase in potential sales of the mobile version of Fortnite.

In addition to casual gaming, Fortnite has also established a following in the realm of competitive gaming, known as e-sports. Fortnite currently advertises more than 125 million players worldwide. Epic Games has offered $100,000,000 to be divided and used as prize money during the 2018-2019 competitive Fortnite season.
