Other mistake: In the ending of the game, "its" is misused in place of "it's" twice in a single sentence ("it's support structure badly damaged collapsed, it's dying echo reverberating", etc). Also, first it mentions that Kingpin's dead and his empire of crime collapses over time gradually, then in the last sentence it makes clear that he's not dead at all.
Character mistake: At the end of the penultimate stage, Frank menacingly says "Kingpin! Your LUCKS finally run out."
Character mistake: Before the final boss fight, The Punisher admonishes him saying "It's all over Kingpin, YOUR through."
