Metal Gear Solid 2: Substance for the PlayStation 2 is the expanded version of the stealth-action title Sons of Liberty. It functions as a "Director's Cut," offering the original cinematic story alongside a massive suite of bonus modes and gameplay challenges.
The Main Story
The game is split into two main chapters. The Tanker chapter follows the veteran soldier Solid Snake as he investigates a new Metal Gear prototype. The much longer Big Shell chapter introduces Raiden, a rookie operative tasked with rescuing the U.S. President from a terrorist group known as "Sons of Liberty." The gameplay is famous for its tactical depth, allowing you to drag bodies, hide in lockers, and use a first-person perspective for precise aiming.
Substance-Exclusive Additions
What sets this version apart is the sheer volume of extra content:
- VR Missions: Over 350 specialized training levels that range from basic sneaking and weapon proficiency to "Variety" missions that involve defending targets or fighting giant soldiers.
- Alternative Missions: Over 200 missions set within the main game's environments, focusing on specific objectives like bomb disposal, photography, or "Hold Up" challenges where you must catch guards off guard.
- Snake Tales: Five standalone, non-canonical story missions where you play as Solid Snake instead of Raiden. These focus on action and are told through text-heavy briefings rather than the series' typical long cinematics.
- Skateboarding Mode: A PS2-exclusive mini-game using the "Evolution Skateboarding" engine. You can skate around the Big Shell as Snake or Raiden, performing tricks and collecting items.
- Casting Theater: A mode where you can swap character models in specific cutscenes, leading to humorous results, like replacing a villain with a different character during a serious moment.
Key Enhancements
Beyond the new modes, the game features refined graphics, updated thermal goggle effects, and a new set of collectible "Dog Tags" to find by holding up enemies. It remains the most complete way to experience the second chapter of the Metal Gear saga on original hardware.
