This would work much better in 3D, but it still sounds awesome. Most of it would still be easy enough using Flash, except the animations, which would take days to make, especially since it would involve taking existing images and manipulating them for every different sprite, which you would probably need over 100 of for each kill, and then adding the blood and gore, which would have to be drawn in to add realism, so one would have to hire more than one artist, and now we're getting expensive.
