It makes you wait for what you want by giving you something you don't expect. He's a cliche in concept, but Prototype 2 goes through a lot of effort to prove he's human, and it does so in an interesting way. Prototype 2 gives players a clearer view of Radical's original intentions through the eyes of James Heller, an emotionally ravaged veteran with nothing left to live for. In turn, Prototype 2 represents a retry of sorts – not because the original was a failure, but because its excellent vision fell a bit short. By positioning Mercer as the villain he truly is in Prototype 2, developer Radical displays an honest understanding of the first game's flaws. The limp attempts to humanize Prototype's protagonist only highlighted how unlikable the reckless sociopath truly was. Alex Mercer was a top tier knob with few, if any, redeeming qualities. It's as if 'he's an a-hole' is a good enough personality trait to make someone care about a character.
Developers rarely show the human side of angry anti-heroes.
