in a "super deformed" art style, in contrast to the original game's realistic style. Like the original computer versions of Snatcher, it was only released in Japan. It abandoned random encounters and introduced a first-person turn-based battle system where the player can aim at specific parts of the enemy's body with guns. Such a battle system has rarely been used since, but similar ones can later be found in the role-playing games Square's Vagrant Story (2000), Bethesda Softworks's Fallout 3 (2008), and Nippon Ichi's Last Rebellion (2010). In 2007, J. C. Fletcher of Engadget said that Kojima's choice to stylise the character designs "was some postmodern playfulness from Hideo Kojima [...] downplaying the dramatic aspects of his game and overlaying obvious video game conventions on top of it", and connected that to a similar playfulness in his later games.

The game has received positive reviews from retro-reviewers. IGN notes that Metal Gear 2 introduced stealth mechanics such as making noise to attract guards, crouching and crawling on the ground, disarming mines, and enemies having view cones. After memory limitation issues prompted him to take a break during the development of Snatcher, Kojima began to explore concepts for Policenauts. He wanted the game to remain in the adventure genre, feeling it was the best method to express what he wanted with video games. He was also growing frustrated with game development and wanted "a way to take creative control back from the programmers". After the release of Metal Gear 2: Solid Snake (1990), he developed a scripting engine so he could decide when animations and music played instead of the programmers.
