Big Boss Stage 01
- Greater number of guards compared to Normal
- Greater number of cameras compared to Normal
- Available ammo pickups are greatly reduced
- Snake takes maximum damage from enemy attacks
- You have 2 ration capacity to start, 3 after Owl, 4 after Havoc (Normal maxes at 5)
- On the bridge, it is recommended to hug the right hedge before entering the screen, and do a small zigzag (1 to 2 steps to the right). This avoids getting spotted by the first guard, while running past the final pair of guards. This is a very small frame buffer.
