Let's be adults about this, the game sucks, anyone that doesn't agree is lying to themselves.
Treyarch can not make a call of duty game to save their lives (see World at War), Activision needs to dump them before they destroy the COD name.
Now for the review... where to start? The graphics as you have probably heard are horrendous, I mean really bad, whats the point of having Hi Def TVs and next gen systems to see graphics that could pass on the PS2.
The sounds and overall presentation suck as well, everything looks "off" is the best way I can put it. The guns don't handle at all realistically and all shoot about the same.
The multi player in this game is as broken as anything you have ever seen. Probably the worst aspect of this is the spawn system, you will constantly be getting shot in the back, or see people spawn right in front of you, its whack. The frame rate and the feel of the game is slow to the point that it is noticeably frustrating.
To conclude, Black Ops does introduce some cool aspect to the franchise (wager matches, customization are the most noticeable), but none of that can make up for how horribly rushed and frustratingly bad this game really is.
