Ok, so where do I begin about how much I despised this game? Diving straight in there with the big one: The Multiplayer.
The gameplay is very formulaic and the COD franchise continues with its trend of overpowering certain weapons so that you end up screaming at the TV and snapping the game disc, because of one guy who camps in a stupid spot (which there are plenty of on the new maps) and shoots at anything that moves. The graphics and sound quality are very poor compared to what you would expect from a best-selling HD franchise. The 'love it or hate it' quick-scoping is back, and there is no shortage of people who love nothing more than running around on the tiny maps blowing your head off with a weapon that is supposed to be fired from half a mile away.
Moving on to the singleplayer, the campaign is very cliched and predictable, which makes it hard to feel sympathetic towards the storyline or the characters especially at one certain point in the game (I won't spoil it for you if you don't have the game). The storyline itself makes very little sense unless you have played Modern Warfare AND Modern Warfare 2, and is very hard to keep track of when playing through. There were too many pathetic, cliched plot twists in a short amount of time.
Finally, the special ops section is a marginal improvement over the spec ops of MW2, but the survival mode gets very tedious and repetitive if played for too long. It gets extrememly frustrating in later stages and is only vaguely fun if you have someone to play with and just feel like messing about. You're stuck with the same tiny maps that you get on multiplayer, and the riot shields now have a habit of breaking after being shot 5 times.
Overall, this is a very terrible FPS and an absolute disgrace to the entire franchise. The addition of Sledgehammer's physics engine has not really helped in any way, and if you are considering buying this game, reconsider and buy something else like Battlefield 3 or Operation Flashpoint. Rant over, thank you for taking the time to read this review and I hope you find it useful in helping you save money on what seems like an expansion to MW2.
