Metal Slug 5 is a run and gun video game for the Neo-Geo console/arcade platform created by SNK Playmore. It was released in 2003 for the MVS arcade platform and is the fifth game in the Metal Slug series. The game was developed by Noise Factory/SNK Playmore, after Korean company Mega Enterprise had directed Metal Slug 4.
The biggest difference from previous titles is the addition of the slide move, which allows the player to evade and maneuver in a new fashion. Unlike its predecessor Metal Slug 4, which reused many of the backgrounds from the previous games, Metal Slug 5 incorporates a wealth of new environments and backgrounds and features a more Heavy metal influenced soundtrack. It was later ported to Microsoft Xbox and Sony PlayStation 2 along with Metal Slug 4 as a compilation. It was also ported to PC specifically for a Korean release.
A special disc that contains deep and intricate secrets about the Metal Slug project is stolen by a mysterious group called the Ptolemaic Army, whose specialty lies from within archaeological excavation and espionage. Marco and Tarma of the Peregrine Falcon Strike Force follow in hot pursuit against the group and in the process are joined by Eri and Fio of SPARROWS. Together once more, the quartet investigate the shrouded objective of the Ptolemaic Army.
