The Metal Slug franchise originally launched on SNK's Neo Geo hardware in 1996 and has since seen multiple ports and re-releases.
The most recent numbered entry in the series, Metal Slug XX, arrived on PSP in 2009; the team notes that 17 years have passed without a new mainline title.
SNK's internal organisation for the reboot includes representatives from development, marketing, sales and licensing who meet regularly to coordinate the project.
Seungju Song, the Metal Slug brand manager who was born the same year the first Metal Slug released, told Nikkei that the company holds cross-departmental meetings roughly twice a month to align work across teams related to the franchise.
Song also said he coined the phrase "MISSION REBOOT" to encapsulate the team's commitment to revitalising the series and emphasized the long gap since the last numbered release as a motivating factor.
Veteran developer Kunihiro Ono told the outlet that desire to bring Metal Slug back has long existed within SNK and that the 30th anniversary provided an ideal moment to formally announce development.
Ono presented the reboot as both a celebration of the franchise and a signal of SNK's serious, company-wide commitment to a new mainline project.
Naoto Abe, who supervises licensing and the 30th anniversary activities and who was part of SNK's Neo Geo launch team in 1989, said he oversees a broad slate of anniversary and external licensing efforts.
Abe also clarified that the release of a Metal Slug reproduction cartridge timed with the upcoming Neo Geo AES+ console was not planned as an anniversary stunt, calling the simultaneous timing a coincidence.
Song framed the team's goal plainly: SNK aims to deliver the content fans want while rebuilding and growing the Metal Slug brand with a long-term perspective.
With the project publicly announced and anniversary activities underway, the series' next steps will be watched closely by long-time fans and retro-hardware enthusiasts alike.
