The Flood are fictional parasitic alien life forms in Bungie's Halo video game series. They are introduced in Halo: Combat Evolved as a second enemy faction alongside the Covenant, and return in Halo 2 and Halo 3 to fill the same role. The Flood are driven by a desire to infect any sentient life they encounter, and are depicted as such a threat that the ancient Forerunners were forced to kill themselves and all other sentient life nearly 100,000 years before the beginning of Halo in an effort to starve the Flood to death.
The Flood's design and fiction was spearheaded by Bungie artist Robert McLees, who utilized unused concepts from the earlier Bungie game Marathon 2. The ringworld Halo was stripped of many of its large creatures to make the Flood's appearance more startling. Bungie environment artist Vic DeLeon spent six months of pre-production time refining the Flood's fleshy aesthetic and designing the organic interiors of Flood-based space ships for Halo 3.
The player's discovery of the Flood in Halo: Combat Evolved is a major plot twist, and was one of the surprises reviewers noted positively upon release. Also, in Halo: Combat Evolved, Characters of Halo gets turned into one of the flood in the 2nd to last level. The Flood's return in Halo 2 and Halo 3 was less enthusiastically praised. Reaction to the Flood has varied over the years; while publications such as The Dallas Morning News found the Flood too derivative and a cliché element of science fiction, Wizard Magazine and PC World Magazine rated them among the greatest villains of all time.
