Development
The aspect of the Metal Slug series was to create a simple, but exciting side-scrolling shoot-em-up game with a very easy control scheme (one joystick and three buttons). The same team that created Metal Slug for the Neo-Geo previously created a handful of games for Irem which have very similar graphics and gameplay. GunForce (1991) and In the Hunt (1993) had noticeably similar gameplay, with graphics that have a slight resemblance to Metal Slug. Gunforce 2 (1994), another title by Irem, had a similar gameplay as Metal Slug. Because of this, some fans refer to Gunforce 2 as "Metal Slug Zero".
Some of the stock sound effects from Irem titles were used in the Metal Slug games. The art style is done by Meeher and the music is composed by Hiya!. They worked on Undercover Cops before forming Nazca.
However, the first 3 titles were developed by the Nazca team before SNK declared bankruptcy.
It is believed that composer Takushi Hiyamuta (Hiya!) was a designer for Sammy Corporation's Metal Slug-style arcade title, Dolphin Blue, when his name was displayed during the ending credits.
After Playmore retained intellectual rights to all SNK titles, the characters Trevor and Nadia no longer appear in future installments because they were created by the Korean-based Mega Enterprise.

Famous quotes containing the word development:
“They [women] can use their abilities to support each other, even as they develop more effective and appropriate ways of dealing with power.... Women do not need to diminish other women ... [they] need the power to advance their own development, but they do not “need” the power to limit the development of others.”
—Jean Baker Miller (20th century)
“For the child whose impulsiveness is indulged, who retains his primitive-discharge mechanisms, is not only an ill-behaved child but a child whose intellectual development is slowed down. No matter how well he is endowed intellectually, if direct action and immediate gratification are the guiding principles of his behavior, there will be less incentive to develop the higher mental processes, to reason, to employ the imagination creatively. . . .”
—Selma H. Fraiberg (20th century)
“As a final instance of the force of limitations in the development of concentration, I must mention that beautiful creature, Helen Keller, whom I have known for these many years. I am filled with wonder of her knowledge, acquired because shut out from all distraction. If I could have been deaf, dumb, and blind I also might have arrived at something.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
