IGN - Developers rarely show the human side of angry anti-heroes. It's as if "he's an a-hole" is a good enough personality trait to make someone care about a character. Alex Mercer was a top tier knob with few, if any, redeeming qualities. The limp attempts to humanize Prototype's protagonist only highlighted how unlikable the reckless sociopath truly was. By positioning Mercer as the villain he truly is in Prototype 2, developer Radical displays an honest understanding of the first game's flaws. 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.
