1999 + 6 = 2005.
It is a chronologically late game in the Metal Gear universe and can be played at its timeline point or third [after "Metal Gear 2: Solid Snake" (1990)] as part of a retro release order experience or entirely separately.
This game was heavily remade and re-released March 9th, 2004 as "Metal Gear Solid: The Twin Snakes" for the GameCube system with a tweaked script, a few new voice actors, and a dramatic change in graphics realism.
The time setting is unchanged.
