He currently works as a freelance artist, remaining fairly active on Japanese art website Pixiv, and has contributed illustrations to Mobius Final Fantasy and Street Fighter V: Arcade Edition.

Kazuma Kujo, credited as KIRE-NAG in the first Metal Slug, went on to form Granzella after leaving both Irem and Nazca, but declined to comment on the status and identity of key staff members including lead designer Meeher and graphic artists Akio and Susumu.

While he was responsible for the design of the gameplay, he left Nazca prior to Metal Slug's release due to internal disputes but has maintained friendship with the developers.

Due to the common use of pseudonyms in arcade titles to hide identities, details of its staff remains scarce but various individuals have been important figures in the history of Nazca Corporation: Atsushi Inaba, formerly of Capcom and current CEO at PlatinumGames, was a member of Nazca after leaving Irem, doing income management, then SNK after its acquisition, rekindling his interest in video game development.

Although details were never delved, Inaba stated he did programming work on a Samurai Shodown title and was unhappy with his experience at SNK.
