Assassin's Creed Brotherhood

Assassin's Creed Brotherhood features online multiplayer and singleplayer mode .
It's singleplayer is truly amazing , so does it's multiplayer .
In multiplayer , you can get Perks (such as autobash), Abilities (such as Hidden Gun or Smoke bomb) and Costumes for Characters . It also features maps like Montergionni and Florence . You can level up until level 50 .
In singleplayer now , you have Ezio Auditore Da Firenze from Assassin's Creed 2 and you continue the story to defeat the Borgia .
Here is a picture of the game :

Call of Duty Black Ops

Well , i have been playing Black Ops for quite a lot time on the Wii and it is AWESOME .
Now , i'm gonna get this on the PS3 , and i hope that it won't be "broken" (Laggy) .
Anyways , the game is much better than Modern Warfare 2 in my opinion . It might not be better than Modern Warfare (1) , but it is still one of the best CoD games . It features (obviously) new maps such as Nuketown(my fav map :P) , Jungle , Array , Summit and many others .
Of course , it also has new weapons , such as MAC 11 or AK74u .
However , many people call the AK74u "n00bweapon" and OverPowered . I must say that i disagree with that since i believe that AK74u becomes overpowered only with the Rapid Fire attachment .
I highly recommend you getting Black Ops on the Wii . About PS3 , we will see ...
