Not at all too difficult if you've played GRAW1. A bit linear, but with very interesting and dynamic missions. Thumbs up

I strongly disagree with the review that it is too difficult. It's a tactical shooter so you cannot hold shift button run through the map and kill everyone yourself. Even though when did that on 'normal' to test if it's too difficult as the review said, I killed 12-15 enemies before a sniper shot me. AI of your team mates is really good, but I've noticed that all NPCs in the game have a bit slow reaction time, thus making me able to kill 12-15 of them in COD4 style combat. This makes you often react much faster than your team, so you'll have most kills in almost every mission, unless you specifically guide your team and sit back at a safe distance.
Concernig multiplayer, I've played coop for about 3-4 hours and found out that since it is without music, can be a bit dull at some moments, especially if there aren't many people on the server. However, missions in multiplayer are more difficut since there's no cross-com, which makes them interesting and addictive (lots of vehicles to destroy, and many sudden surprise attacks).
Great game, and a great sequel!
