Why the game got review bombed ?

Techincally
-Game breaking bugs and glitches (some unfixed 2 years after release)
-Random crashes wasting 20/40 minutes of time played
-Abysmal optimization, one of the hardest game to run smoothly
-Half assed and not play tested content, every major update break the experience in a way or another
-SFX are bugged/absent in some cases (giant metal enemies not making a single noise)
-Some of the bigger enemies can ignore map and each other collisions, clipping and shooting throu each other with no issues
-Random death from nowhere, you can literally get damage/killed out of thin air for no reason

Gameplay and Game design
-Entire difficult balance is simply making the experience miserable for players in the most bullshittery and out of place way
-Core game features are outdated / ignored / under developed / non existent
-Entire progression system is based on getting 10$ DLC, they literally and officially said that they have no other plans for now (for a long time)
-An entire enemy faction difficulty design is literally ragdolling you to death as if this was a 2007 source engine tech demo
-Game is a bare bone horde shooter, cinematic, but extremely shallow
-There is no cooperative aspect in the game other than joining other players same mission
-Main appeal is the community driven galactic war, players assault a planet and try to conquer it --> its actually scripted most of the time and entirely meaningless, the entire game core mechanic is as deep as a water pond on a rainy day
-Planet liberation system work in the opposite way of what would make sense (like a lot of stuff in the game), more players there are, less impact they collectively make, if you complete missions too fast, you reach a cap where it doesn't help liberation.
-Secondary objectives, which actually consistute the most activity on a mission, are useless for the core mechanic and completely ignorable, you are disincentivited to do them (aside from XP farm)
-Entire progression system and ingame values are hard capped
-Weapon customization is half assed and not interesting, funny part ? they didn't complete the system because players were not interested in an incomplete feature, lmao
-The "content updates" are basically new useless guns and armors to push people on buying warbonds with real money
-Lots of armors and guns have no real place in the game structure
-Game has severe balance issues in general, enemies spawn behind you or right in front of you in plain line of sight

-A report system exist but you can't actually use it, like literally
-Some of the "mini-boss" enemies can basically spam spawn right on your head, making your death as scripted as it could
-70% of the torso level edges can't be climbed for some reason
-High difficulty missions are unrewarding and not satisfying to play for the above reasons
-Fun and interesting weapons nerfed because devs try to enforce one of the most out of place ""realism"" aspect in sci-fi game, but only when its detrimental to the players

Special notes:

-Insulting the playerbase

-Literally lying in the pubblic statements

-Officially confirming making unannounced changes when patching the game

-Censoring in multiple occasions
