General overview


  • Four Triple Joined arms
  • Recycle biomass

Method of attack:

None, only used to transport.


The Flood Transport Form, also known as the Sweeper, was a Flood Pure Form.[1] Unlike the Carrier Form, which carries and incubates Infection Forms, the transport would carry a maximum of six unarmed Combat Forms to a particular destination.


Physical Description & Physiology[edit]

The sweeper would have had four triple-jointed limbs to move its load of troops around, and featured numerous tentacles to consume or recycle biomass, dead or alive. The sweeper also boasted a biomass re-processor that converted recently-consumed biomass into rapid-growth embryos or Combat Forms.

Biomass Conversion[edit]

Before the Sweeper, or Transport Form, released its cargo, it would pass four steps, specifically:

  1. The Sweeper would pick up and collect any available biomass with its tentacles, whether an already assimilated Flood entity, or a sentient being.
  2. The biomass was then put inside of the Sweeper, and consumed for internal recycling.
  3. When enough biomass was consumed and processed, the Sweeper's blisters would begin to form and then proceed to grow within the creature.
  4. The Sweeper would then cough up and shoot the blister into the air.


  • This was seen in The Art of Halo 3, though it was cut from the final version of Halo 3.
  • The transport form may have inspired the Flood Stalker Form, as the body shape is similar between the two.
