Darque, the controls are freaking stupid.
There's no reason that you shouldn't be able to move around like in a normal third person shooter, if they were so keen on ensuring that you could walk backwards as well as forwards, change the mapping of the controller so that the L trigger when held down makes the control stick function like it already does. I can kind of sort of understand why you can't shoot and run at the same time (builds tension) but that is stupid as well, better to make you accuracy take aheavy hit when running and shooting, so it's not worth it. The way it is now just breaks my suspension of disbelief and makes me think "Hey I'm playing a game!"
I should totally be a game designer at Capcom as my ideas would work better than theirs.
EDIT: Also if you use the L trigger as a toggle, mapping the Y button as what it does currently would work fine, as the only thing L trigger does right now is Auto Aim and Defense. Defense isn't done unless you're all in the Zombie's arms already, and the firing while using auto-aim can be pulled off easily enough by rolling your thumb.
The graphics are still beautiful though.
