All gameplay footage with commentary
According to Colin the framerate is pretty stable running from 28-33fps.
Unreachable background areas like mountains you see far away ect ect have been removed.
Some areas that would have 13 enemy's on PS3 would have 10 enemy's on Vita.
Enemy's no longer ragdoll when killed, they instead explode.
I assume this is due to ram limitations, but it seems pretty damn good for a handheld imo
