Stealth is the cornerstone of Metal Gear Solid 2. Learn to use cover effectively, observe enemy patrol patterns, and use distractions. Avoid direct confrontation whenever possible. Remember that sound plays a significant role; running on metal surfaces or dropping items can alert nearby guards. Patience is your greatest weapon.

- Observe Patrols: Watch enemy routes before acting.
- Use Cover: Hide behind objects and walls.
- Crawl: Reduces visibility and sound.
- Distractions: Throw magazines or empty magazines to draw guards.
- Chokeholds: Non-lethal takedowns from behind.
- Camera Awareness: Look for and disable security cameras.
