Metal Slug 4 ARCADE
About Metal Slug 4
Metal Slug 4 is SNK’s 2002 run-and-gun, the first entry in the series developed primarily by Noise Factory and Mega Enterprise rather than the original Nazca-descended SNK team behind the first three games, following SNK’s 2001 bankruptcy and reorganization. It introduces new playable soldiers Trevor Spacey and Nadia Cassel alongside series regulars Marco and Fio.
Its shift in developer is frequently cited by longtime fans as a turning point for the series’ difficulty and level design, which many consider less refined than the original SNK-developed trilogy despite carrying over the same core run-and-gun structure, vehicle-hijacking mechanics, and hand-animated sprite style the series had established.
