After a boring afternoon of searching for the highest quality version of the Metal Gear Solid codec and alert/found (!) sounds for the purpose of making a ringtone for my iPhone, I decided to make my own. I promise you that these are the highest quality samples you will find. Highest fidelity and I let you choose from multiple file formats (in case you wanted the ringtone for a different phone). As a bonus I have included the flashback sequence sounds from Metal Gear Solid 4 as well. Hope you enjoy! :)
