 Like " The Last Voyage of the Infinite Succor " , " Breaking Quarantine " deals with the Flood outbreak that occurs during Halo . While " The Last Voyage " tells the story from the Covenant perspective , " Breaking Quarantine " highlights the escape of the human soldier Sgt. Johnson from the Flood . Johnson is a minor personality in Halo : Combat Evolved who becomes an important character in the following two games ; while the novel Halo : First Strike explains that Johnson resists Flood infestation due to a medical condition , no other story up to that point explained how Johnson escapes . " Breaking Quarantine " is an example of Bungie 's attempts to expand the story arcs of secondary characters that would have no opportunity to go explained in the main storyline . Unlike the other stories , " Breaking Quarantine " contains no dialogue , only weapon sound effects , which are rendered in Japanese . Both art and story were provided by Tsutomu Nihei , a manga artist and architect who based his illustrations directly on the structures found within the game .
