Metal Slug 3

Thanks to the super-human effort or Marco and Tarma, as well as Eri and Fio, the second coup d'etat of General Morden who advocated the "contruction of a New World Order" has been defeated. Contrary to their wishes after this battle, Major Marco and Captain Tarma, who were instrumental in crushing Morden's Army, were ordered to assume leadership of the Peregrine Falcons Squad (PF Squad) after their requests for discharge were ignored. The abilities of these two are still deemed necessary to wipe out the remnants of Morden's army scattered throughout the world.

While Marco and Tarma raged their fearsome war against the remnants of Morden's army, a rash of strange occurences broke out all over the world. These included abductions of livestock, abnormally lage shellfish and beetles, and kidnappings of of leading figures of various countries. Sensing that a fearful presence other than Morden was involved, the Intelligence Agency of the Government Army was prompted to develop and carry out a mission that forced special-ops unit SPARROWS and PF Squad to work together. Previous investigations by the Intel Agency led to one undeniable conclusion: "alien intelligence" was behind all of this.
