Always the reluctant hero, Snake is once again out to save the world again from evil forces that have landed their hands on the venerable Metal Gear technology. This time around, Kojima and his team did plenty of research while making MGS2 to guarantee its authenticity. They took regular tours of submarines and aircraft carriers in Japan. They traveled to New York for some footage (and sightseeing), but also got to inspect the NYPD Bomb Squad and secured footage of their equipment. The team went so far as to go through mock tactical missions in their own office building, under the supervision of their military advisors, to ensure whatever they put into the game was accurate.
