Ah ha! "But what if you just turn the auto-targeting off?" you ask. Well then, if that's the case, then Call of Duty turns into exactly the sort of unresponsive FPS you'd expect it to be -- with your enemies moving at twice the speed you do, and your slow-mo guns trying their best to keep up.
Regardless of how you approach Roads to Victory, though, it still doesn't change some of the game's other fundamental problems. Enemy AI is the world heavyweight champion of dumb -- often running in place or getting caught in a standstill with its gun drawn at its own downed ally. Moreover, your fellow teammates will stop out of nowhere to create sudden impassible walls with their bodies at bottlenecks, and the stages themselves are the very definition of linear. Other than the US bombing raid, there isn't a single scenario that captures our imagination the way EA's Medal of Honor Heroes did.
The bomber scenario is definitely the most interesting mission you'll find.
Other disappointing things to consider: Unlike the previous Calls of Duty, this one doesn't offer any characters that matter; the storyline doesn't follow anyone in particular and everyone seems to have the exact same personality in no matter what your country or situation is. It's also rather annoying to see that some German soldiers can occasionally do some truly inhuman things (shooting through concrete sticks out in particular).
Here's what Call of Duty does right: Even though it has all the issues mentioned above, its sense of atmosphere can't be denied -- you definitely get the sense that this is World War II (albeit on a tiny little screen), and its faithfulness in recreating the console versions is admirable. Roads to Victory also has some of the best sniping mechanics I've seen on the PSP yet, and it's too bad that there aren't more chances to use them.
As a big fan of previous Call of Duty titles, I found Roads to Victory to be the definite low point of the series. While diehard followers should enjoy the entertaining ad hoc multiplayer options and the second-best representation of World War II on PSP (Medal of Honor Heroes still has first), the game's major mechanical problems, technical hitches, and lack of true customization make it "just another shooter" instead of the standout blaster its console counterparts are.
