It's not bad but it does not feel like playing the old game at all to me.
The Maps are the same and they feel like the originals. The flow is really nice and visuals are amazing.
But gunplay and vehicles especially are just like 2042.
Yes you cant slide or go prone in bc2 but that doesnt change the fact that the movement is still more similar to 2042 than bc2.
That's ok for the most part but saing it's like the old games is just wrong.
The vehicles also have the new physics. Air does really feel different from their originals.
Also the lack of some very popular upgrades like the TV missiles in BF3 do just feel wrong.
Also the classes are just like the specialists but with restrctions in their loadout.
You cant pick up a class from dead soldiers. Only the weapons. You cant use perks like in BF3. the classes have set passives.
Overall the mode lacks in gameplay detail to be really compared to the originals.
The design team for the maps did an awesome job tho!
