Good find on Snap to Cover system

I haven't played too many games with this new system and did some research on it and came up with this website. Makes me wonder since Socom 4 is already 3rd person what is the need for it since you can already see around corners and so forth.. Don't get why it needs to be in the game after I researched it.
