I had the exact same initial impression, tbh. I went in kind of thinking it would be very Battlefield. It feels like a very very simple Battlefield. I didn't play the snow map with the vehicles though, only the other one. Still, you first start out just a rifle and nothing else and, from using that, it felt very simplistic. I guess the no recoil, no reloading just makes the game feel too basic.
But, damn, if it isn't extremely pretty.
