Metal Gear Solid is a stealth game created by Hideo Kojima which follows the MSX2 video games Metal Gear and Metal Gear 2: Solid Snake. Despite a transition to 3D, Metal Gear Solid's gameplay remains similar to his predecessors. The game utilizes a traditional top-down view and the player must navigate the protagonist Solid Snake through the game's areas without being detected. Detection will set off an alarm which draws armed enemies to his location. Conversations with Snake's allies and cutscenes are used extensively to advance the plot and gain more insight into it. Metal Gear Solid is regarded as one of the greatest and most important video games of all time, and helped popularize the stealth genre and in-engine cinematic cutscenes.

Metal Gear Solid takes place in an alternate history in which the Cold War continued into the 1990s, ending at some point near the end of the 20th century. Coming out of retirement, special agent Solid Snake is called back into the line of duty to take on rogue members of Foxhound, a crack government anti-terrorist squad threatening to launch nuclear-weapons on the White House unless they receive their $1 billion ransom. With only 24 hours to sabotage Foxhound's threat, Snake must infiltrate enemy lines, rescue the two hostages and thwart the terrorists' plans. The demons of his past will challenge him and his will as a soldier shall be tested, as Snake fights to save the world from nuclear devastation.
