Possibly, the trophy you get for killing him is called murder your maker or something with a ? on the end, as sort of a hint that he could have possibly survived. Mercer couldn't consume Heller in the story, so I don't believe Heller could do the same. Many popular theories are that Mercer is alive inside of Heller. Will just have to hope for a Prototype 3 to find out the true fate of Mercer, personally I hope he's alive and takes on the role of protagonist again.
Yes, but you will play as Sgt. James Heller instead, who will use his powers (similar to Alex Mercer's) to kill Alex Mercer.
