Didn't live up to your unrealistic expectations. It's an action game with multiplayer based around mechs.

For this type of game the industry evolved to shoving loot crates, skins, and battle passes down our throats, not a "great story". This game has none of that. Which I'm sure most people are happy about.

The "story" in Armored Core exists to give you a reason to play their mech action game. Mech action being the focal point. It gives you a reason to play the game, get used to the controls, and then maybe play some multiplayer.
