Feel like a lot of the low ratings are by people who misunderstood the concept of the game. This is a "Realistic" MMO/RPG/ACTION/FPS.
If you come in here expecting a battle royale or call of duty you're going to have a bad time.
Instead realize this game is something different, with a lot more to think about, for those that are detail oriented and interested in extremely high risk/loss games then you will enjoy this. If you are a casual player who doesnt like to spend more than an hour or so gaming in a session this will probably not be the game for you.
90% of the 1 star reviews I read are honestly just people who didnt know what they were getting into, and did not take the time to learn or didnt care. Thats fine as different strokes for different folks but that doesnt mean the game is "bad"
