I don't know if there is another topic on this...or if there is any official info on it.....But I have an idea to what the next game should be like. Imo, Helller dies and his daughter inherits the power along with something new that will allow her to clean up the city. She will be assisted by Mercer's sister.
Its all I can think of to make sense out of a possible sequel... Any other ideas...knowing what we have thus far?
It shown be shown that Heller didn't consume the real Mercer. Then Mercer teams with Heller to put an end to things once and for all. With Mercer being the main playable character and Heller being the support character who radios in what he's doing and only shows up in important cut scenes.
