Yay finaly a WH40K collab!
I rate it 7/10.
Voice acting - It was well... quite bad. For example some of the voices didn't fit the characters (the british marine and the blood raven) I pledge to do some acting for fantasy collab. I believe my skills are at least a bit better than those in the collab. ( must do a demo, for now watch my flash. NOTE: I am capable of doing much more)
Graphics - some were really great, specially from flashbound18 and BoMbLu
Humour - it was OK
Size - c'mon it's ridiculous. Street figther has 28.5 and much much more content. Don't do the same thing with the fantasy collab.
Preloader - Very good...for the first 5 times later you have to turn the volume off because the flash is loading so long. BTW I have made a WFB themed Newgrounds logo with a steam tank.
My favourite part was with the Terminator reference.
Hope this review helps.
