Microbial Colonies or Sprawl Colonies are energy clusters of the Archæan Parasite featured in Tom Clancy's Rainbow Six Extraction.

Background[]

The Microbial Colonies have mutated and risen in different Sub-Zone areas across different Regions. These Colonies served as the first critical event that caused REACT to activate their Crisis Protocol and take action against in order to maintain containment of the Chimera Parasite.

Behavior[]

The Colonies serve as a storage unit for energy clusters and while resting dormant, they get charged up. When Microbial Colonies feel that they are being threatened, they retaliate by sending swarms of Archæans to thwart the attackers that mean to destroy their source of energy. When being attacked, the energy within the Colonies gets channels even more into the Parasite, increasing its aggression towards the attackers. Having three different variants also gives the Parasite an offensive edge when preparing to defend the Colony.

Due to the Colonies producing so much energy, it causes the Sprawl that it generates to become more resistant. Though the mutated Sprawl doesn't impede an Operator's movement, it cannot be removed like normal Sprawl and will regenerate until the Colony itself is destroyed by the canisters. Since the Sprawl has covered the entire Sub-Zone, this allows it to spawn Archæans in any area without the need of Nests.

Gameplay[]

The Sprawl Colonies were introduced as the main objective in the Crisis Event, Spillover. Colonies come in three variants that players must fight against: Elite Archæan Colonies, Cloaked Archæan Colonies, and Blinding Spore Carrier Archæan Colonies.

Nine Sprawl Colonies, three of each variant will rest dormant within a Sub-Zone until they are attacked by players by using the new Dissolution Agent Canisters. As a defense on the attack of their colonies, the Parasite will continuously spawn large swarms of Archæans to overwhelm the attackers and target the device that is destroying the Colony. Each section the players progress through, the more aggressive the Archæans get and spawn stronger levels. The variants of the Colonies act in a similar manner as the Parasite Mutations in an Incursion.

Elite Colonies will occasionally send Elite Archæans during the attack, taking the players focus off the lower level enemies to attack the stronger Elite, giving the lower level enemies a chance to attack the canister. Cloaked Colonies will send Archæans that are fully cloaked, making it harder for players to judge where their current positionings are and take the opportunity to slip by and attack the objective. Blinding Spore Carrier Colonies will swarm the players with Archæans covered in Blinding Spores, distracting the players and impairing their vision, taking the chance to capitalize with their defense.

Brief "The apparition of the Sprawl Colonies in an enigma. By analyzing their remains after dissolution, REACT should be able to learn more about their purpose." - Thermite
Logbook Crisis Log SPL: "We've got one mystery solved surrounding the Sprawl Colonies: We've learned that the Parasite stores energy reserves within them. They get charged up when the Parasite is dormant. That fuels them for later. When a Colony is attacked, it channels even more energy, which heightens their aggression levels..." - Thermite

Brief "A larger amount of Sprawl Colonies samples will help us understand their purpose. We need to dissolve more of them." - Thermite
Logbook Crisis Log SPL: "We have a breakthrough! The colonies appear to be working as an evolutionary reaction to the Parasite's environmental stress, resulting in a more controlled and aggressive response. If this continues, the zones will be overwhelmed by their numbers and Archæans could breach our containment protocol. We have to stop them from spreading." - Thermite
