As Fortnite continues to suck in gamers by the millions, Epic Games has worked hard to keep the game fresh and entertaining, whether players are dropping in for the first or thousandth time. Last month, it committed more than $100 million into Fortnite tournament prize pools and announced its first official esports event: the Fortnite Pro-Am. Popular streamers and YouTubers -- with backgrounds in PUBG, League of Legends, Counter-Strike: Global Offensive, Call of Duty and, of course, Fortnite -- joined actors, sports stars and musicians at E3 for a 50-team, 100-person battle royale. Tyler "Ninja" Blevins, the biggest personality in competitive esports right now (helps when you stream with hip-hop megastar Drake), buddied up with EDM DJ Marshmello, YouTuber Ali-A joined Fall Out Boy singer Pete Wentz, while professional gamer Gotaga was accompanied by UFC fighter Demetrious Johnson in a bid to win a $3 million charity prize pool. Before now, enterprising organizers had hosted their own Fortnite eSports tournaments just using the default game.
