I like it, and I have no idea what you are talking about the shotgun not being power full enough, it is perfect if you are close they die if you are far the shotgun doesn't do much. The pistol is perfect exactly like how it was in SiN 1.
Melee is also useful if you are close to an enemy. What animations are being redone, nothing and textures well one wooden crate isn't going to be different from another one. Do you want them to redone the fire as well and the water somehow? jesus.
Anyways some screens here:
