Metal Gear Solid reportedly gave players the option to knock out foes like guards without killing them, but at minimum still required players to have to bump off some of the bosses to get through the whole game.
Metal Gear Solid 2 introduced a new asset that made it even less mandatory to kill enemies: Possibly taking the hint provided long ago by the 1980's Sega arcade game "Tranquilizer Gun," the game gave players just such a weapon, making it possible to eliminate all but two enemies (both bosses) by tranquilizing them.
Metal Gear Solid 3 apparently raised the bar by making it possible to defeat all bosses without kills, but apparently still caused a "scripted kill" to take place, in which the game's lead character kills one of them (even if the player had already exerted the effort to defeat them with non-lethal methods).
Finally, however, 2008's Metal Gear Solid 4 raised the bar even higher and became the first genuine zero kill run Metal Gear Solid game, in which players could win the entire game without bumping off even a single boss with lethal means.
In addition to lots of stealth gameplay and nonlethal weapons, Metal Gear Solid 4 offers players some very cool-sounding nonviolent assets such as an OctoCamo suit to mimic the appearance of surface textures to evade detection, and even a FaceCamo to mimic the faces of other characters in the game.

Apparently Kojima had already publicly announced that he wanted to retire after directing Metal Gear Solid 3, but was persuaded to return for MGS4 after what Wikipedia described as "substantial negative fan reaction, including death threats."
