Could use work, but...
I liked enough to be moderately interested. The blood animation in this one was much better than the first and I must say that the action had a great overall improvement; there was a point where a guy was shot while launching himself through the air that made me go "OOOOOOHHH!!!". However, there was one HUGE flaw that interferes with my enjoyment of this series so far. I understand that each one has a different story to it, but THERE IS VIRTUALLY NO CLUES GIVEN AS TO WHAT THE HELL IS GOING ON. I couldn't tell who was what or vice-versa. I'm still not sure if that guy who broke the glass to get a shotgun was suddenly betraying his comrades or was a crazy person.
You get 7 because it's quite obvious you worked hard to better this one and it's just neat, but -3 for the lack of minimal plot guidance.
