This game is lacking in nearly every aspect. The game has really good mobility and the flying is fun for a while and graphically it is very impressive. But that is about all it has going for it.
The quests are uninspiring and repetitive. They dont feel different from any other quest. While generally these games always boil down to kill waves, activate and defend and what not. The environment around them doesnt make them feel different at all and the storyline does not make each mission feel unique.
The game has very little content, when you compare it to a game like the Division, that has dozens of missions and events that feel unique due to the environment around them being specifically designed to fit that mission, the game's level of content is a shame.
Weapon selection and skill customization are a joke when compared to other games on the genre and everything is centered around RNG. Unlike other games that allow you to transfer traits from one item to another to still have a sense of progression and counter bad RNG, this game allows for none of that.
Enemy variery and AI quality is incredibly lacking, it feels like you are playing against an AI from 10 years ago, and end game is really non existent. Pretty much all the content that is "end game content" is something you have had access to through the leveling campaign.
