Pros:

-Looks nice both first and third
-Red dot
-New Animations, good too

Cons:

-Nothing really

Conclusion:

I love it, but I feel that there is something missing when I'm using this gun.

Pros:

-Nearly every track has been replaced with miku music
-What makes this mod so great is how well the music is placed, for example, how there is mean music being played when tank shows up, and the depressing music when you or all members die, or the happy/victorious music that plays at the end of finale
-THE HORDE KILLING SONG
-concert 

Cons:

Hell No

Conclusion:

Best audio mod here on this site, no question about it, if u love miku, u will love this
