Your standard run to this point do something, run here single player but an addictive MP makes up for bugs and SP.
The real meat of this game is in its multiplayer and zombies mode where both of which are great and the biggest problem one could come up with is the fact most players around launch were unable to play these modes due to bugs and odd glitches and system spikes that caused the game to not run as well as it should even though players systems clearly met specs. (As of this review that problem still has not been fixed) but like the MP contains all the perks and leveling up options like the last except this time you win money from matches to buy attachments and guns and dont have to use the weapons to customize them simply get to a high enough level to purchase the guns themselves everything else is availble from the get go from perks to equipemnt you simply pick and purchase the ones you wish.
Zombies has continued the story from the last map and expanded into including a set of new characters in a new map called five and an arcade style top down survival mode called dead ops. The zombie elements retains the same formula of kills and hits for points and points for guns if you liked the first nazi zombies this will be no change and likely very satisfiying only problem being is the game search filter system seems pointless as no matter what you pick it sticks you with whatever party it feels like. So get ready to say hello to high ping and australlians probably.
A good game and solid addition to the Call of Duties the bugs take away from the experiance as a high selling points to myself is having a solid and stable game to play multiplayer on.
