Modern Warfare 3 maintained the old style of CoD series with No improvement from its predecessor
Now get back to the review part, I will start with the good of this game using point form.
The Good :
-Dramatic storyline (as always) continuing the story of MW2
-Great experience of single player gameplay (as always) which will draw yourself into the game.
-Low system requirement (its can run on my 5 years old lappy)
The Bad :
-No Improvement, you will thought yourself playing MW2
-Shorter Single Player (I finished it in 4 hours)
-Old style of singleplayer gameplay, enemy will just keep on respawn until you complete current objectives
-Ending is bit disappointed
-No new features in Multiplayer
-$60 multiplayer map pack
-New killstreaks system
-Dull Multiplayer gameplay, you just have to run around and shoot ,you don't really need a team.
-The multiplayer maps are getting difficult and smaller, the oppenent will come out of nowhere to shoot you
-Outdated graphics
-No destructive environment like the new BF3 or BFBC2
-Only support up to 16 players
Conclusion, I spent my $60 to enjoy playing the single player story but get big disappoint on the multiplayer, there no new from MW2.. if you are not get into CoD MW series yet, you are good to buy this game, otherwise I advise you to save up your money from buying another map packs
