"" deals with a rapidly aging Solid Snake (now branded "Old Snake") who is on a mission to find and defeat Revolver Ocelot, now known as Liquid Ocelot. Despite the destruction of the Arsenal Gear in "Sons of Liberty", the Patriots have continued in their plans to influence the course of human history, installing artificial intelligence systems around the world. Ocelot, opposed to this, has assembled armies with which to fight back and intends to hijack their entire operating system for his own ends. Solid Snake's objective later changes to destroying the AIs of the Patriots and stop their oppression. After he and his allies succeed, Snake decides to live out his life peacefully.
