Samus finds the room filled with pesticide.

Industrial-grade pesticide is toxic green gas used by the Galactic Federation to rid areas of unwanted creatures. Seen only in Metroid Prime 2: Echoes, it suffocated a group of Splinters in Hive Chamber A. Three Federation Marines were also killed when they could not escape due to a malfunction with Gate A1's locks. When Samus Aran enters Hive Chamber A, the pesticide is still being dispensed. However, it cannot harm her, presumably due to her Oxygen Supply Equipment protecting Samus from inhaling it.

Development notes[]

The fog from the pesticide was achieved with three texture cards, being scaled in and out. This allowed for the appearance of fog without using traditional fog volumes, which would have affected the game's performance.[1]
