| ||For the events before the Battle of the Mineshaft and the battle that led to this battle, see Battle for the Nuclear Power Plant.|
The battle of the mineshaft began when Caine captured the power plant to feed the Gaiaphage uranium and turned off the power completely in Perdido Beach. As Caine broke in, they attacked the guards, killing Brittney, one of the guards. Sam, Brianna, and Dekka arrive and fight Caine, Drake and his army.
The battle ends outside the power plant. Drake is about to crush fuel rods, which would eventually kill everyone in the FAYZ. Caine finally gains common sense and uses his telekinesis to supposedly kill Drake, but not before Diana is put out of action.
Then, Sam and Caine come up with a plan to defeat the Gaiaphage. Sam asks Brianna to go get Duck. Next, Sam, Caine, Edilio, and Duck go to defeat the Gaiaphage. Lana (possessed by the Gaiaphage) shoots Edilio, so Sam, Caine, and Duck head on. Sam creates a Sammy Sun, so they can see, and then Duck asks Caine to throw him at the Gaiaphage as hard as he can. In the air, Duck uses his power to change his density to become heavier than a mountain, and hits the Gaiaphage, knocking the Gaiaphage to the bottom of the FAYZ. However, Duck dies in the process. When Sam and Caine come out, Lana heals Edilio, Dekka and Diana.
