Your accent kind of got in the way. Were yo trying to pronounce "Apocalypse" that way? Once crap started gonig down, things got a bit confusing and the voices were pretty similar. The recording isn't that bad and the acting itself was pretty good. I think someone who scouted you for their animation would be pretty lucky. Good job.
Lots of yelling! I like the music. The voices though are well, kind of lacking. I'm having trouble trying to exactly pinpoint this but they all just don't feel real to me. The toddler was rather amusing and anything with Tom Fulp in it has to be good.
Your acting started out a bit weak, but that was probably intentional since it went up a whole level when everything went to hell. Everyones voices fitted their characters personality pretty well, great old man voice, but the commandos voice changed throuhout the beginning and end zombie apocalypse with a newgrounds twist, a bit orginal, but still a zombie apocalypse I'm amazed you managed to do all that screaming without destroying your microphone quality.
