What really hurts this game is the same thing that has plagued any FPS title released for the PSP.  No developer has yet to figure out a decent way to compensate for the lack of that second stick and it shows here in a big way.  This game does offer four different configurations, but I found the default to be the best of the bunch, using the face buttons to aim.  Since the game has a pretty friendly auto-aim feature this is the easiest way to line those nasty Nazis up in your sights.  Because the developers know that the controls basically suck the enemy AI has been toned down to the point that the Germans you're fighting seem to have arrived at the battlefield on the short bus.  Working through fourteen levels of their predictability and ineffectiveness gets old very quickly.

Graphically the Call of Duty series has always been ahead of the game and this game does look pretty darn... pretty on the PSP.  There are a good number of enemies onscreen (not as many as the consoles), and there is always a lot to look at whether it's explosions, raining debris, smoke, or other various ambient eye candy.  Unfortunately there is not a lot of inventive detail in those graphics, however, and a lot of the environments wind up looking the same from one level to the next.

Altogether Call of Duty: Roads to Victory is a take it or leave it entry for the PSP.  If you really want to get your WWII shooter fix on in a portable format it will suffice for a while, but there's nothing that makes this game stand out as a must play title and there are a lot of little things that may prove more annoying than enjoyable.
