I finally finished Modern Warfare.

My only minus is the whole "peek on a corner, shot people" only amused for so long. The enemy isn't specially bright or strong and going gung-ho assure you will die pretty fast, which made for a slow, not very action-ish game in the end.

"All Ghilled Up" was the best mission of the bunch, but I will make a special mention for the final chase. Very chaotic and very fun (although I think I could survive by just keeping crouched the whole trip)

After this mission, the story start focusing solely on Soap,and the game pace pick up and gets more interesting. I will definitely try the sequel to see how it develops.
