The Covenant (level)

The Covenant is the tentative title of the seventh campaign mission of Halo 3.

It takes place in a "citadel", as discovered in the beta. This citadel is possibly and probably forerunner, considering the emphasis on Forerunner buildings present in non-Halo environments. If this is true, this the citadel is most likely The Ark.

Upon completing it on the Normal, Heroic, or Legendary difficulties, the player will earn the "Last Stand" achievement and 40 Gamerpoints.

Trivia

 * "Last Stand" can also be compared with the "Last Stand of the 300 (Spartans)."
