Bad design and plenty of bugs.
Character design feels like a free to play mobile shooters with cringey voice lines. WIthout class system, everyone are using basically the same weapons and you will get killed by PP 10 times in one single game. I think it will be very hard to balance this game in the future.
Movement and controls is a major step back from BFV. You can barely move when in prone/crouch, and there is no under water swimming.
Map design is horrible. Large open map make it impossible to travel by foot. Breakthrough is good for WW2 setting, but feels wired in modern setting especially with those tall buildings as target area.
UI design is confusing, and the color scheme should change.
And the destruction is very limited and generic compares to BF4/BF1/BFV. I think they made a mistake removing the fortification system in BFV.
If you want to have a games similar to previous BF titles, BF 2042 will be a huge disappointment, because it feels more like apex/fortnite/cod kind game than a classic BF title.
If you enjoy shooters such as apex/fortnite/cod, you probably shouldn't buy this game either. Because apex/fortnite are free, and are way more polished that 2042 at this point. COD and other shooters are cheaper and have way more features.
In conclusion, I don't this game is worth the $60 price tag, there are better games with similar gameplay that are cheaper or free and more polished. And I honestly regret the purchase and cannot think of any reason for anyone to purchase this game.
