Metal Gear Solid 2

Metal Gear Solid 2: Sons of Liberty is a 2001 stealth game directed by Hideo Kojima and published by Konami. The sequel to 1998's smash hit Metal Gear Solid, Sons of Liberty follows… not Solid Snake, but a rookie spy codenamed Raiden, who infiltrates an offshore cleanup facility to stop a group of terrorists from causing an environmental disaster. Metal Gear Solid 2 features advanced enemy AI that will search potential hiding spots and check on missing soldiers, on top of introducing new mechanics like climbing along ledges, first-person aiming for all weapons, and peaking around corners, making the stealth gameplay even deeper than in prior entries. Thanks to all of those improvements and a complex, labyrinthine plot that delivers poignant warnings about the future of the digital age, Metal Gear Solid 2: Sons of Liberty is now considered to be one of the greatest video games ever made.
