Very good game...
The game has nice graphics, it's not as good as Crysis...But it's much better looking than the original Doom...
Online is very fun and there is noone else so you never die...
The game is on DVD, so you have to have a DVD drive to install it...It comes in a beautiful DVD box and it has written Conflict Deined ops on the side of it, so you'll have no trouble finding it among your other games games on the shelf...
The game is very well optimezed and I didn't have any framerate issues, running fluently at 60 fps from start to finish and it has guns you can shoot and grenades and lots of explosions...It's a very good game...
