Snatcher is a cyberpunk graphic adventure game developed and published by Konami. It was written and designed by Hideo Kojima and first released in 1988 for the PC-8801 and MSX2 in Japan. Snatcher is set in a future East Asian metropolis where humanoid robots dubbed "Snatchers" have been discovered killing humans and replacing them in society. The game follows Gillian Seed, an amnesiac who joins an anti-Snatcher agency in search of his past. Gameplay takes place primarily through a menu-based interface through which the player can choose to examine items, search rooms, speak to characters, explore a semi-open world, and perform other actions.

Kojima wanted Snatcher to have a cinematic feel, so the setting and story are heavily influenced by science fiction films, like Blade Runner, Akira, The Terminator, and Invasion of the Body Snatchers. Development on the PC versions took more than twice as long as the average game of the time, even after Kojima was asked to trim more than half his initial story.

The game was released to positive reviews, but poor sales. It garnered a cult following, and was remade as a role-playing game called SD Snatcher for the MSX2 in 1990. This was followed by a remake of the original adventure game using CD-ROM technology, released for the PC Engine Super CD-ROM² System in 1992. The game was originally only in Japanese. In 1994, Konami developed an English Sega CD version of Snatcher specifically for Europe and North America. Although it was a commercial failure in North America, the Sega CD version received mostly positive reviews. There is also a fan English translation for the MSX version.

Snatcher has been retrospectively acclaimed as both one of the best adventure and cyberpunk games of all time, and identified as a foundation for the themes Kojima explored later in the Metal Gear series. The game was a significant inspiration on Goichi Suda, who worked with Kojima to produce a radio drama prequel, Sdatcher. Snatcher was last rereleased in 1996 on the PlayStation and Sega Saturn. The game was also included in the PC Engine Mini in 2020, though only playable in Japanese. Its lack of availability on modern platforms has surprised industry analysts, given the game's legacy.

Snatcher has been described as both a graphic adventure game and a visual novel. The player controls Gillian Seed as he investigates and hunts "Snatchers", dangerous humanoid robots disguised as humans roaming Neo Kobe City. The game's visuals are static images with some animations that display at the top of the screen. There is no point-and-click interface, with all actions made through a text menu with commands such as move, look, and investigate. The game's puzzles and dialogue trees are simple, lending to an emphasis on linear storytelling. Sometimes character panels are shown below the main graphics window during conversations to convey their facial expressions.

The game allows exploration of a semi-open world. There are a handful of action segments where the player shoots at enemies dispersed across a 3x3 grid. The Sega CD version supports the Justifier light gun packaged with Lethal Enforcers for these segments.

Snatcher is set in the mid-21st century, fifty years after a biological weapon known as Lucifer-Alpha killed much of the world's population. In Neo Kobe City, a metropolis on an artificial island in eastern Asia, humanoid robots dubbed "Snatchers" have been recently discovered killing humans and replacing them in society. They use an artificial skin that is nigh-impossible to tell apart from regular skin. The Neo Kobe government quarantines the city from the outside world and establishes JUNKER, a task force to hunt Snatchers. The player takes on the role of Gillian Seed (Yusaku Yara/Jeff Lupetin), an amnesiac who can only remember that his past, along with that of his estranged wife Jamie (Kikuko Inoue/Susan Mele), is somehow related to Snatchers. He starts working at JUNKER in hopes that hunting Snatchers will bring his past to light.

After arriving at the JUNKER headquarters, Gillian Seed meets Mika Slayton (Miina Tominaga/Kimberly Harne) and Chief Benson Cunningham (Gorō Naya/Ray Van Steen), and receives a robot navigator named "Metal Gear Mk. II" (Mami Koyama/Lucy Childs) from JUNKER's engineer Harry Benson (Ryūji Saikachi/Ray Van Steen). Metal Gear receives a distress call from Jean-Jack Gibson (Isao Inoguchi/Jim Parks), the only other JUNKER agent, so Gillian travels there with Metal Gear, only to find a pair of Snatchers have beheaded him. They try to pursue the Snatchers, but are forced to make a quick escape as the factory explodes. Gillian begins searching for the identity of the Snatchers that murdered Jean-Jack, and after searching his house with the help of his daughter Katrina (Miina Tominaga/Lynn Foosaner) and speaking with his informant "Napoleon" (Gorō Naya/Jim Parks), Gillian identifies a pair of suspects. When hunting down the Snatchers, he is nearly killed but is saved by Random Hajile (Kaneto Shiozawa/Jim Parks), a Snatcher bounty hunter.
