I wouldn't really consider the game dead, as there's millions of players still playing.
I used to play PUBG and Fortnite a lot, and I consider Apex to be one of the best BR games to exist.
I remember around the launch of Apex there wasn't really anything fun to do, there wasn't any challenges or no battle pass. You would just play a game, win or die then repeat.
But nowadays it's pretty fun, there's challenges and a battle pass and more legends to play as. And also events and etc.
they just hit 70M players last october. starting the global series and making good changes to the ranked systems. its slowly getting better and better.
