Level up your weapons enough during the game proper and you can destroy each segment, working your way towards the torso of whatever mechanical beast the programmers have thrown at you this time. If a game has bosses in it, we want multiple hit zones, the ability to cripple a giant beast with a well-placed shot. If 1998-tech could do it, then we're sure Xbox 360 and PS3 can give us some amazing area damage - and not just on bosses. We don't want to see any enemies take a whole magazine of bullets and then fall over any more. Every shot should affect them in some way. And we want score bonuses for doing it right.
