a divider in the center. The game is playable with or without the Solid Eye. When switched into Solid Eye mode, the game displays two images on either side of the PSP screen. When used with the Solid Eye, the images overlap and produce a pop-out, 3D effect. The game and manual warn that using this device for extended periods of time may lead to eyestrain, and prolonged use is not recommended. As more cards are collected, videos are unlocked in the Solid Eye Theater, available from the game's menu. These videos are only viewable as Solid Eye footage, and showcase videos of Japanese women as well as cut scenes from Metal Gear Solid 3: Snake Eater. Acid 2 is capable of communicating with Metal Gear Solid 3: Subsistence for the PlayStation 2. By connecting a PS2 to a PSP, it is possible to take photos in Subsistence and transfer them to a PSP for viewing in 3D with the Solid Eye. The manual that is included with the American version of the game is significantly thinned down, and as such, does not contain a specific guide on how to utilize this feature. Instructions can be found in the downloadable manual. Plot Story The story begins with a man known as Snake, a young woman named Consuela Alvarez, and two pilots named Dave Copeland and Roddy Louiz, flying into the United States illegally when they are arrested by the FBI. After being caught, Snake is pressed into a mission by his captor, an FBI agent named Dalton. Snake agrees to the job to free his friends and clear his name with Dalton. Snake's initial objective is to infiltrate a research facility operated by SaintLogic (called "StrateLogic" in the Japanese version), a military arms manufacturer, located on an isolated North American island. Dalton is investigating SaintLogic for inhuman actions towards children, and utilizes Snake's abilities to infiltrate SaintLogic and uncover the truth behind their business practices. Shortly into Snake's mission, Dalton's authority is exceeded by General Wiseman, an official with the United States Department of Defense. Snake slowly learns that Wiseman's involvement is in response to a SaintLogic executive Thomas Koppelthorn, who has made demands that the United States release several prisoners and has threatened to use nuclear weapons. Wiseman proceeds to offer Snake information regarding his past in return for Snake's assistance in eliminating the present SaintLogic threat. Snake teams
