What's the flood in Halo?

Answer 1

quote from http://en.wikipedia.org/wiki/Flood_(Halo) The Flood is a fictional alien parasitic life form in the Halo video game series. They are introduced in Halo: Combat Evolved as a secondary enemy to the game's protagonist, Master Chief, and return in Halo 2. They are depicted as highly virulent and deadly, and can quickly incapacitate and infect their vectors. The Flood have appeared in three primary forms: Infection, Combat, and Carrier forms, but also have forms such as the Brain form and the Juggernaut form which have not been fully explained or documented. All of these have an attraction to any lifeform of sufficient mass to accommodate them and will try to attack/infect any they encounter.

The Flood made their first appearance in Halo: Combat Evolved's sixth level, "343 Guilty Spark." After reaching Halo's control room in the previous mission, Master Chief is sent by the AI Cortana to try and stop Captain Jacob Keyes and his UNSC Marines from reaching a weapons cache they believed was hidden in a Forerunner structure by a swamp. In reality, the cache was false intelligence; instead of finding weapons, Keyes found that a sizable population of Flood was released from stasis by the Covenant. The Flood quickly escape containment and spread across the ring, threatening not only Humanity and the Covenant, but the entire galaxy if they escape.

The Flood is a parasite that infects both humans and Covenant. It was used by the forerunners and the only way to get rid of it is to starve it to death. In order to do so the forerunners built the Halo rings that had the capability of ridding large sections of the universe of life.
