Metal Gear 2: Solid Snake
Metal Gear 2: Solid Snake is a 1990 action-adventure stealth video game developed and published by Konami for the MSX2 computer platform. It serves as a sequel to the MSX2 version of the original Metal Gear, written and designed by series's creator Hideo Kojima, who conceived the game in response to Snake's Revenge, a separately-produced sequel that was being developed at the time for the NES specifically for the North American and European markets. The MSX2 version of Solid Snake was only released in Japan, although Kojima would later direct another sequel titled Metal Gear Solid, which was released worldwide for the PlayStation in 1998 to critical acclaim. This later led to Solid Snake being re-released alongside the original Metal Gear as additional content in the Subsistence version of Metal Gear Solid 3 for the PlayStation 2 in 2005. It was also included in the HD remastered ports of Metal Gear Solid 3 released for PlayStation 3, PlayStation Vita, and Xbox 360, and was given a standalone re-release in Japan as a downloadable game for mobile phones and the Wii Virtual Console.

A stealth game is a type of video game in which the player primarily uses stealth to avoid or overcome opponents. Games in the genre typically allow the player to remain undetected by hiding, sneaking, or using disguises. Some games allow the player to choose between a stealthy approach or directly attacking antagonists, but rewarding the player for greater use of stealth. The genre has employed espionage, counter-terrorism, and rogue themes, with protagonists that are special forces operatives, special agents, secret agents, thieves, ninjas, or assassins. Some games have also combined stealth elements with other genres, such as first-person shooters and also platformers.
Tom Clancy's Splinter Cell (2002) featured a light-based visibility meter which determined how much the player was visible.
Metal Gear Solid 3: Snake Eater (2004) introduced camouflage to the stealth genre as can be seen with the "camo index" in the top-right corner.
