New gameplay mechanics include a Gears of War-esque "blind-fire", an advanced melee system that allows Gabe to use enemies as human shields, and 360 degree underwater combat. "Interactive moments" akin to those of God of War and Resident Evil 4 will also add a dash of cinematic thrill.
Logan's Shadow has a lot of impressive technology behind it. Aside from the visuals, it's also one of the few PSP titles (if not the first) to utilize the Havok physics engine made famous by games such as Half-Life 2. With such impressive production design, it may be Syphon Filter that becomes PSP's big "killer app," not God of War. Check out the images below, and then a video after the cut.
