A retread through World War II
Aside from the very-difficult last two levels (last western against Germany and last eastern against Japan), most of this game is pretty even... evenly mediocre.
The little bits of polish that Treyarch decided to add (hi, Jack Bauer, I mean, Sgt.) were nice, but the Medal of Honor series simply did this game better with its iteration several years ago.
I never touched the multiplayer, as I usually stick to multiplayer-only games for that kind of fun. Therefore, this score should only reflect the single player campaign.
