There's nothing new about this Call of Duty: Black Ops shit.
I've been a COD fan since 2 was released on the 360 at Launch. It got me through the weak launch and was the best game by far of all the titles that came with the 360. COD 3 (made by treyarch) I didn't like much due to the vehicles, leave that shit for Battlefield or Halo, and just wasnt as fun as 2. Modern Warfare was something extremely fresh something new and was extremly addicting, this is when COD took over the FPS thrown and became the juggernaut that it is.
Then a year later as they do with every COD game now, came COD WaW (made by treyarch), which was ok i didnt think this game was that great either lots of bugs online (people shooting you from under the map wtf!) and seemed like they couldn't come up with thery're own material felt like a WWII version of MW which was made by infinity ward. MW2 was released last november i believe, and lived up mostly to the giant hype that was accumulated by fans and press. It added Pro Perks that added abilities to your online soldier, specific challanges, and a new co-cp challenge mode.
Now with the recent release of Black-ops which I only played for a short time, I really didn't see anything new in the multiplayer (didn't play the story which I heard was good). There was nothing at all that was new in Black Ops over MW2. I actually noticed things they took out like some of the perks and death streaks. I recently sent the game to Jimmy so he could give it a try and write his opinion on it, and if i know him he wont be on it for to long. Long story short if you have MW2 keep and just buy the map packs, I dont believe Black-Ops is worth $60 for a copy of MW2 in which I believe the multiplayer is much better, plus you wont have to deal with so many 9 year old nuabs screaming into the mics, since they'll all be on Black-ops.
