In "The Siren's Deception", the player would have only been fought by 2 of the women in Gweden Farm, with the third, Faustina, fleeing to the basement. There, the player would have had multiple dialogue options with her, and ultimately been able to spare her. In the final game, you must fight all 3 women on the first floor with no option to spare any of them. These lines were found in the German version of the game.
