The stealth genre had already been re-defined by two of Hideo Kojima's epic masterpieces from the 1980's; Metal Gear and Metal Gear 2: Solid Snake on the MSX-2 home computer, two games that were crucial in revolutionizing the stealth game forever. But it was 1998's Metal Gear Solid that gave real credibility to the genre, maximizing the sneaking with a compelling storyline that allowed it to become a modern classic. Its dark undercurrent of a powerful anti-nuclear message is matched up expertly with the in-game sneaking, which features some of the most fantastic and rewarding stealth mechanics you'll ever hope to find. Cardboard boxes become a mobile hiding place, encouraging player improvisation and the tension is just high enough to keep you sharp for the entire experience.
