Halo 3 - the complete story

Level five:

The story: Ask anyone for their favourite moment in Halo history and one will probably pop up more than most: the introduction of the Flood. Lacking any real impact in Halo 2, Bungie are back in the terror game here, as Level 5 sees the destroyed city of Voi overrun with the parasitic mites, becoming FloodVoi. Is this what forces the Arbiter and Chief to team up?

The evidence: Master Chief and the Arbiter must team up against the Flood, cleansing the city. We've still yet to see any sight of the Flood for Halo 3, although their return is confirmed by Bungie. Our prediction? These suckers will be ugly, as they take control of the Covenant, marines and civilians in the surrounding area.

The gameplay: Expect one of the most cinematic moments in the game, as two groups of soldiers led by the Chief and the Arbiter have to abandon their feud to combat the undead parasites swarming the city. It'll be a case of work together, or die together. Bungie will want to outdo themselves on every level, and odds are... er, they will.
