Sorry if this has been posted before, but it's not really as interesting as it sounds. I was fighting Shang Tsung today, with a person that could impale Shang with their weapon. Anyways, he was down to no health, but he performed his soul steal move. While performing that rule, he ran out of health. But his soul steal was still in progress, and once it was completed, he got back some health, even though he was already in his "defeated" sway. I couldn't pull off a fatality, but he eventually collapsed, still with some health left. Thought it was kinda a neat glitch :D
