Titanfall-themed free-to-play battle royale title Apex Legends has been played by 50m people since its launch four weeks ago.

The milestone was announced by the CEO of developer Respawn Entertainment Vince Zampella via Twitter (below), who also said that "there's much more to come".

In the last two weeks, the game's user base has doubled, continuing what can only be described as a very successful launch. Within eight hours of release, Zampella said that one million people had played the game. By the end of its first day, that figure had tripled to three million. Within three days, Apex Legends boasted 10m players before hitting 25m in its first, er, fortnight.

During its first month, Apex Legends was watched for 131.7m hours on Twitch alone, according to tracking and analytics site Sullygnome. Where at launch the game boasted a massive lead on rival Fortnite, now the gap is much closer with Fortnite having been watched for 93.2m hours in the same time frame.

Apex Legends launched ahead of EA's financial call for the quarter ending December 31st, 2018. While the company's results disappointed investors - and its share price dropping - stock soon rebounded as news of Apex Legends' success broke.
