History of Methane Flush

Methane Flush was a Lost Sector in the New Pacific Arcology on Titan, reached from Siren's Watch. It was guarded by the phase boss Karugul, which moves further into the Lost Sector each time it takes enough damage. Its enemies were Hive forces of Savathûn's Brood.

It was a first-appearance Lost Sector in Destiny 2 and was also active during Forsaken. It was removed from the game alongside Titan with the release of Beyond Light.
