It's a far better game then either PUBG or Fortnite in my book. I never liked the third-person perspective or fort-building that is so essential in Fortnite, and PUBG still doesn't run all that well. It's a game that tries to do "lightweight Arma" yet somehow manages to be more clunky then that massive game.
This game does a lot better. It inherits the speed of its Titanfall heritage, it inherits the distinct weapons (now with ballistics rather then hitscan), but it also adds new things: Communication using entirely in-game prompts is the best I've seen in any game to the point it makes voice chat and text chat redundant. Even with a squad that fully knows eachother and is on voice, the ping system is still extremely good at relaying information.
It's siginficantly less frustrating in dying too: where in PUBG being downed is a near-game over where you wait a few seconds until your inevitable execution, in Apelegs you still have a decent chance to shield yourself and get back to safety, and even when you die you can be respawned by your teammates after the battle is done. This makes the game far less frustrating then its counterparts.
Please do try it. There's no harm with it being free to play after all, and Respawn deserve their big breakthrough.
It also completely undercuts the Battle Royale mode that Dice was creating for Battlefield. Turnabout is fair play
