Well, with Hot Gun gone (didn't really care for it, was hit and miss for me), I would expect better sound effects, especially the footsteps. The generic potato chip bag footsteps in confrontation were easily drowned out by every other sound.
It's also kinda silly for everyone to have some sort of "spider sense".
I haven't been on Socom for a while, I'll try to make it, but with other games to play and stuff going on...
