Metal Slug 4 (c) 2002 SNK Playmore.
The popular series of side-scrolling action games continues, introducing all-new characters into the plot. The world is now trembling under the fear of cyber terror, as the birth of a deadly new computer virus threatens to snatch the main military system out of every country. The virus has been created by the terrorist group known as Amadeus, and must be stopped by the four main heroes in the story. They are : Marco Rossi, an army platoon leader; Fio Germi, a superior director of an Italian secret service; Nadia Cassel, a French regular army soldier; and Trevor Spacey, a regular army sergeant. In the game introduction, the team discover that Morden is still alive and probably behind Amadeus...
