The Collectors have moved in and retaken the Reactor on Cyone after Shepard had cleared Reaper forces earlier in the war. Alliance intel has discovered that the Collectors are using the reactor to power a new hive base currently under construction within the facility. Intel has also detected extremely lethal levels of radiation within the facility, any organic being sent in would die within seconds. The Alliance has thus sent in a Geth Pyro squad to eliminate the Collector forces preventing them from redirecting power and reactivating the fuel production, opening desperately needed fuel supply lines to the Joint Galactic Fleet. This Fuel Supply Depot is one of the most important refueling locations in the galaxy. It cannot stay under the claws of the Collector Bugs. Burn out the Collector Forces and the hive they have started constructing to the ground. Clear out the radiation to allow the repair teams in the facility. The Bugs Must Burn! Eliminate them all with extreme Incendiary prejudice. Even one collector can disrupt reactor operations.
