What was the subtitle of the 2006 expanded version of Metal Gear Solid 3?

The 2006 expanded version of Metal Gear Solid 3 was titled Metal Gear Solid 3: Subsistence.

Subsistence added a number of features to the original Snake Eater release. Its most notable gameplay change was a freely controllable third-person camera, replacing the more restricted viewpoint used in the original game. The edition also included additional content and online multiplayer in its initial release.

The package contained the original Snake Eater campaign along with expanded modes and historical series material. It became the principal enhanced edition of Metal Gear Solid 3 for many players.

The subtitle is easy to confuse with Metal Gear Solid: Integral, the expanded version of the first Metal Gear Solid, or Metal Gear Solid 2: Substance, the expanded version of the second game. Those are separate releases with different added content.
