This wasn't bad at all, and as the intro is flashing by I'm wondering why it didn't recieve a high score, but when the real animation starts it seems there are a few things to improve. First, a better flow of events. The red thread isn't always clear, it feels like it doesn't really follow a logical series of events, it kinda jumps from character to character, and the voice acting doesn't always hint at what's going on, at what it's about, at what can/will happen or what you should look forward to/fearetc.
The voices aren't bad, nor is the animation (though it does feel overly closed-in, seeing some scenes from a distance would be nice, not just close-ups of faces, at times zoomed-in close-ups of faces, at times close-ups of guns, etc... only the fight at the end is a little zoomed out, but it's still really close in. Maybe that's why you don't really grasp the situation. Looking forward to see how future episodes turn out, keep it going!
