OK, TONS of maps, played for 2 hours and played the same maps maybe twice. There are tons more places to go within the maps, buildings, roofs etc. And they are really big.
Guns early on a very similar to each other IMO, waiting for one that I LOVE. Tons of kill streak perks, some are interactive that you can control. Haven't gotten one but have gotten very close.
Ground war and TDM is all I played and Ground war can get very hectic. TDM on the big maps is interesting. A really good sniper can completely own the place.
Pretty good.
