The Making of Metal Gear Solid 2: Sons of Liberty(2003)

As Solid Snake is about to undergo another sneaking mission, he gets a call on his Codec. Expecting Otacon, he proceeds to answer and explains that he's about to start the mission. However, the caller is actually revealed to be Hideo Kojima, who requests Snake's help as he fears his project had been leaked. He then proceeds to explain the development process alongside a narrator, also using some game footage.
