Apex Legends continues to put up impressive numbers, from one million players shortly after it went live to 2.5 million in the first 24 hours, and now 10 million players—and one million concurrents—in just 72 hours.   

"This has been a truly incredible journey. We tested and tweaked. We argued and agreed. We got to a point where we felt some magic. We knew it would be risky to take the franchise in this direction, to go free to play, and do a surprise launch. But we fell in love with Apex Legends and wanted, needed, other people to play it too," Respawn boss Vince Zampella wrote in an update.
