Fortnite's standalone Battle Royale mode launched yesterday for PlayStation 4, Xbox One, and PC, and despite objections from PlayerUnknown's Battlegrounds developer Bluehole, it's already off to an impressive start. Today, Epic revealed that more than one million players played the title on launch day.

Like PUBG, Battle Royale is a 100-player survival game set on a single map that closes in as the game progresses. Players are dropped onto the map via a "battle bus" and are armed with only a glider and pickaxe, with the objective being to outlast all the other players and be the last one standing. It's this similarity--and Epic's admission that PUBG inspired it--that caused PUBG developer Bluehole to speak out against the game last week.
