Floodgate (Level)

Cleansing is the tentative title of the fifth campaign mission of Halo 3.

It takes place in Voi, Africa, as does the preceding mission, The Storm. It is also believed that the player fights the Flood at Voi, as the level was encoded in the beta as "floodvoi."

Upon completing it on the Normal, Heroic, or Legendary difficulties, the player will earn the "Cleansing" achievement and 30 Gamerpoints.
