    Information on The Metal Gear Solid Codec

    The Metal Gear series has brought many gaming concepts & items to the forefront of our collective consciousness. Like the cardboard box before it, the Codec device plays a large role in the early MGS titles, becoming synonymous with the series. This article tries to provide information on the Metal Gear Solid Codec as well as providing a listing of the various Metal Gear Solid Codec frequencies the player can enter during the main franchise of games. Read on for the full listing of these frequency numbers and who engages the player in conversation when they have been input into the Codec.

    Codec 003   Prior to Metal Gear Solid, the Codec was yet to be invented by technical adept Mei Ling, however Snake would utilise a radio transceiver for communique with Big Boss et al. This changed in the Playstation MGS release, with the introduction of both the Soliton radar and the Codec mechanics/technologies. The Codec becomes one of the key platforms for Hideo Kojima -- the game creator & director -- to convey important information, dialogue and oft times narrative driven suspense. Furthermore, until the fourth Metal Gear Solid, Codec frequencies were also used to save game (termed ‘mission’) data.

    List of Metal Gear Solid Codec Frequencies

    Codec 002   There you have it, the full listing of Metal Gear Solid Codec frequencies. It is worth pointing out that MGS3 has some extra Codec numbers that can be input, giving the player a health boost, however these just play music instead of having any kind of conversation or plot/character development. Hopefully this list has provided enough coverage to forgo looking at the back of your PS1 box for Meryl’s Codec number or wondering how to escape the cell during Operation Snake Eater.
