Ok, the singleplayer story is lame, but did we buy it for that? Nope!
Online play is as expected and if you don't overdo it, a total blast.
The zombie mode is surprisingly fun and a good change of pace if your having a bad night of getting fragged online. You don't have to play alone either; the coop mode works great and you'll meet some great people along the way.
The "First Strike" DLC is well worth the price and added dozens of hours of life to the original game. New zombie map "Ascension" is a favorite among many. Waiting patiently for the next DLC "Escalation" and it's zombie map, "Call of the Dead"
Long story short; COD:Black Ops is money well spent.
