It kicks major ass , a huge surprise . First of al it is the best looking console fps, it's like playing CGI , the resident evil 5 of first person shooters in terms of graphics. Everything in its graphics is perfect, no jaggies, fantastic lighting and textures and CGI-quality human and gun models. The ultra-linear nature of the game helps to bring the graphical fidelity to amazing heights. Jezus the seond time you visit Vietnam , with the jungle setting is jaw-dropping . Tons of destructuble objects as well.
The game is also visceral , you really feel that you are shooting weapons . The atmosphere is fantastic (best yet in a COD game) and extremely dark making the MW CODs feel like child's play. The story is extremely cool in mixing real life historic characters with a fictonal story.
IMO, the best COD by far and a big rival to Halo:Reach for best shooter of the year.
