Directional Microphone
From the Metal Gear Wiki
The Directional Microphone (D. Mic.) a handheld, long-range sound amplification system. It can be used to penetrate walls and soundproof barriers in order to listen in on sounds and conversations from far away.
The item was used by Raiden during the Big Shell Incident. After he found it in the computer room in the B2 level of Shell 1, he made use of it in locating Richard Ames. Raiden did this by using the microphone to listen to Ames' distinctive heartbeat - a result of his pacemaker. He also used it to eavesdrop on several conversations that he would be otherwise unable to hear, such as that Solidus Snake and Revolver Ocelot, and the radio conversation between Solidus and Olga.
Naked Snake also made some use of the Directional Microphone during Operation Snake Eater. Equipped with it from the start of his mission, it did not serve a specific purpose, but still came in very useful in locating enemies, for lack of a better device. It also proved particularly handy in locating The End during his sniper duel.
The Microphone is listed under weapons when it is equipped. It is operated in first person view, Raiden/Snake holding the device like a pistol. It can be aimed to amplify sound coming from that direction. Any captions transcribing the dialogue of a character it is aimed at change size depending on how well the microphone is targeted at a character (smaller for quieter).
[edit] Trivia
- In Sons of Liberty, the Directional Microphone can be used to listen in on several secret conversations involving Johnny Sasaki (See Secrets).
