Great game and a MUST have if you are a WWII shooter fan.
Now for the best of the game in my opinion. The mulitplayer in Call of Duty Finest Hour is so, dare I say, perfect that its really just a blast to keep playing and hard to turn off. Once you have got to the point where you have the control mechanics for each weapon and know how each of them work most effectively, you will be amazed at how easy but fun it is to frag random people you don't even know. Now there is a couple of downsides to the multiplayer. First, there is no sort of stat tracking which would have put this game over the top for me. Also, there are no friends list/buddy list that some games of its time already had i.e. Delta Force Black Hawk Down and SOCCOM, but you really don't need it that badly if you have a USB headset.
All in all Call of Duty Finest Hour for PS2 is a solid WWII shooter that I even still play today. Its solid action gameplay and addictive multiplayer is what gives this title 4/5 or a 9/10 for me.
You can even look for me online for this game my name is N.A.P.o.M.
