Snake's codec regarding the Ice Climbers begins in Ultimate.

In series tradition, they also tend to 'break the fourth wall', referring directly to their status as characters in a video game. Within the conversations, characters occasionally allude to events and characters from the Metal Gear games. The same voice actors from the original games reprise their roles. Snake's portrait is subtly modified from its original version, reflecting his visible stubble in Smash. Characters within the codecs are portrayed as hand-drawn portraits. The codec's appearance is based on how it is depicted in Metal Gear Solid and its remake, Metal Gear Solid: The Twin Snakes, using the same ringing sound effect from the latter game. By calling certain frequencies, Snake can talk to different characters who specialize in different subjects and roles, including Colonel Campbell, Otacon, and Mei Ling, the three members of his support team who appear in Smash. This Smash Taunt is based on the optional codec conversations that recur throughout the Metal Gear series, where Snake is given information about his current whereabouts, objectives, or actions.
