more enemies to kill. more that don't fight back.
One thing that always bothered me is that the enemies rarely fight back. They might interrupt your combo as you fight a ranked officer, and that's the only challenge in the game. I'm disappointed that the makers thought, "so how do we make it different? I know, more harmless foot soldiers." Granted it's a hack'n'slash, but they need some sort of system. And they could stop using the same engine over and over for each game. There's a reason why a game like DW and COD comes out every year. They might as well charge you a game's full price for an update. There's no difference.
If you love Dynasty Warriors however, you'll enjoy 5.
