The four hardened soldiers (Marco, Tarma, Eri, Fio) were dispatched in hot pursuit to retrieve the important stolen files. Several years later, the heavily funded Ptolemaics were able to use this information to steal the Metal Slug secrets and prepared to take over the world. The Amadeus Syndicate was able to send information (as seen in the credits of Metal Slug 4) to the Ptolemaic Army before their facility got ran out by the Regular Army. Metal Slug 5 Elite's story occurs before the massive invasion of the Ptolemaic Army after the said group stole the Metal Slug Super Vehicle's secret files. The original version said that the game manifested worldwide by the attacks of the Ptolemaic Army, and the stealing of the Metal Slug secrets.
