photometric sensor on the game cartridge, forcing them to play in sunlight. Another team inside Konami, in a collaboration with Silicon Knights, began work on Metal Gear Solid: The Twin Snakes, a GameCube enhanced remake of the first Metal Gear Solid with all the gameplay features of Metal Gear Solid 2 and with cutscenes redirected by director Ryuhei Kitamura. Afterwards, Kojima designed and released Metal Gear Solid 3: Snake Eater for the PlayStation 2. Unlike the previous games in the series, which took place in the near future and focused on indoor locations, the game is set in a Soviet jungle during the height of the Cold War in 1964, and features wilderness survival, camouflage, and James Bond styled espionage. The North American version was released on November 17, 2004, with the Japanese counterpart following on December 16. The European version was released on March 4, 2005.

It was released in Japan on December 16, 2004. Its sequel, Metal Gear Acid 2, was released on March 21, 2006. Kojima wanted Solid Snake to appear in Super Smash Bros.

Brawl was in development, series director Masahiro Sakurai contacted Kojima to work and add Snake and content related to the Metal Gear series, including a stage based on Shadow Moses Island (the main setting of Solid), into the game. Released in June 2008, Kojima co-directed Metal Gear Solid 4: Guns of the Patriots with Shuyo Murata.
