Soliton Radar

The Soliton Radar is used in both Metal Gear Solid and Metal Gear Solid 2 to show the position of the player, and enemies around them. It also displays other important characters and other things, such as Surveillance Cameras.

Explaining the Radar:

To quote Mei Ling: "The bright dot in the middle is you Snake. The red dots are your enemies and the blue cone shape represents their field of vision."

Also, when in first person view mode, a green cone appears infront of the "bright dot in the middle" representing the player's field of vision. When a gaurd becomes suspicious of something (say if the player was to knock on a wall) the blue cone changes to a yellow cone, and if the gaurd notices the player, the blue/yellow cone changes to a red cone.

When in Alert mode, the radar stps functioning. It can also not be used in areas with strong harmonic resinence (e.g. narrow spaces)
