Played this. Seems just like the original, I didn't notice anything really new although I haven't played COD is a bit.
For me, I don't like the random deaths. Tried hardened first, died repeatedly. Went to the lesser difficulty, made it a bit farther, but there's still random shells that can kill you instantly. You'll be doing everything your're supposed to be doing and still die over and over. I was killing krauts with nice sweeping 50 cal work, killing 20x more than any ai, then suddenly BOOM, dead from mortar.
That's another thing, I didn't notice even one single dead kraut from any of the ai. I guess they did kill one or two, but usually it's 20 krauts and I apparently have to kill at least 18 of them solo - even when the ai are only 20 ft away from the enemy, they miss over and over. Kinda stupid.
Won't be buying this. Seems like same COD, just another day.
