I just played a few rounds and to be honest, I like BC2 a lot better. For one, the lag was really bad even on low ping servers, that didn't help any.
I don't care for the new map layout, the one in the bottom corner. I am not really a big fan of the new maps either.
It is still a fun game, I just prefer BC2 over this.
Can you unlock new weapons just like in BC2? I did not have my weapons that I like so that didn't help any. But I do like the flamethrower, it just takes to long to kill them.
