Floodgate (Level)

Cleansing is believed to be the fifth campaign mission of Halo 3.

It takes place in Voi, Africa, as does the preceding mission, Assault. It is also believed that the player cleanses the Flood from Voi, as the level Cleansing is connected with the Flood.

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