The Gecko's nuclear power plant, also known as Poseidon Oil reactor number 5, is a large nuclear power plant that once supplied power to Gecko city.


Entry areaEdit

Once the Chosen One enters the plant, they are greeted by a guard at the reception area. Jeremy is in the supply room on the player character's left, and the entire section is the living spaces for the ghouls, mainly Gecko's glowing ones. Separating this area from the rest of the complex is a checkpoint requiring a yellow pass key to pass.

Yellow areaEdit

This section requires the yellow pass key to gain access and contains the plant's control center, more living areas, including those of Festus, the reactor foreman. He can be pickpocketed for a part requisition form and a red pass key can be found in a locker in the first room on the left after entering the yellow area.

Reactor coreEdit

This section requires the red pass key to gain access, Hank watches over the control room of the reactor from this point, which also contains a computer with the controls for the maintenance robot, and a link to PoseidoNet, which provides the Chosen One access an Enclave security station on the Enclave Oil Rig. He can install the needed part by hand or with the robot, overload the reactor manually or, again, with the robot. Radiation levels inside the core are very high, and radiation-resistant armor, high natural resistance, and plenty of Rad-X and RadAway are vital to survive.

Notable lootEdit


Gecko's nuclear power plant appears only in Fallout 2.

Behind the scenesEdit

  • One of the glowing ones in the reactor will point his finger to the Chosen One and say 'Phone home', a reference to the movie E.T.
  • With 50% Science, during the one-way video conversation with the Enclave communications officer, if the Chosen One responds "Uh, it's working just fine. I can see you," they can also say "Uh, we're all fine here. How are you?" This is a reference to the 1977 film Star Wars IV: A New Hope, where Han Solo tries to deceive an Imperial intercom officer after commandeering a communication station.
