Worst multiplayer ever, good singleplayer...
Graphics - They're simply excellent, the only thing that made me play this for 3 days was graphichs. I would rate them 9 out of 10.
Gameplay (singleplayer) - At the beginning, it's not too bad, interesenting a bit (7/10), but after that the missions get boring.. Everything gets so boring, and driving around all that territory to do a mission that's for example simply scouting is really boring, there's no point in that if you want to enjoy FPS game.. I would rate singleplayer gameplay around 5/10.
Gameplay (multiplayer) - After buying game, I couldn't get the multiplayer to work only for one reason - Ubisoft technical support, if they answer to their messages then it's an automated message that doesn't help ANYHOW.. I couldn't ever get multiplayer to work, meaning I wasted my money. I would rate multiplayer gameplay around 7/10 (by watching videos).
Overall - Game is fun at the first look, but when you start really playing it - it gets boring and really useless. This is VERY buggy game, there are so many bugs that you can't sometimes even finish a game just because a bug prevents you from completing an important mission.
P.S Ubisoft, stop making games if you cannot improve your technical support, you guys at Ubisoft should be thankful to community that they actually rescue you guys by providing "technical support from community".
