The single player was terrible...you teammates had an innate nature of falling off cliffs and getting stuck in the most retarded places. However, i really enjoyed coop b/c my team no longer lacked the ability to "follow" and plus we could finish missions faster.
But the thing I hate most about single player is that if you get shot in a building, your teammates won't help you. Especially in blindside where there's the underground cave filled w/ shotgunning terr, if you get shot, your teammates watch you die.
Also the smoke was just dumb, if you threw it, it should also have the reverse effect on you also, temporarily blocking your view, rather than make it semi transparent and see yourself running around with some stupid mercenaries waiting to get knifed.
Another disappointment in single player/coop was the lack of vehicles in instant action missions. In hte single player Retaliation, you had to walk all the way across 7 times without vehicles and it was extremely tedious. It's dumb how they wouldn't give you even a simple scout vehicle w/o a turrent.
The biggest disappointment is when you finally unlock the r44m pistol, you cannot use it in multiplayer. The description of hte pistol is misleading, because it says you can use it in the classic maps. It took me a very, very long time to beat all the instant action missions and to find out all those hours were wasted, it caused an unpleasant reaction...
