I'm also curious about the differences. I didn't like the second half of the original game when she goes undercover. It would be great if they got rid of that part and focused more on corruption at the police station.
Are you specifically asking about this abandoned version by Phalzyr, or are you referring to one of the other versions that is actually not abandoned (Doshima or Abaddon)?
The answer to your question will vary depending on the subject of your question. lol
