After Chapter IV

In this chapterOn the oil rig, the Chosen One frees the villagers of Arroyo and the residents of Vault 13 held as test subjects.

The final chapters lead through Navarro to the Enclave's oil rig. The base holds prisoners, soldiers and the virus. The Chosen One frees Arroyo's villagers and Vault 13's residents and learns the full scale of the plan. The final confrontation is with President Richardson and Frank Horrigan. After they are defeated, the rig is destroyed and the Enclave loses its main base. The Chosen One returns with the G.E.C.K.

Navarro and the oil rig are the final locations. The Chosen One destroys the Enclave's capability and ends the threat. The Enclave is the sequel's villain because it represents the old world's arrogance. The leaders still believe that America can be restored by removing the people who survived, and the plan is the logical end of that belief.

Frank Horrigan is a tragic enforcer, a man turned into a weapon. His fight is the final duel, but the real victory is freeing the captives and ending the virus. The destruction of the rig is also an end to the war that began in 2077. With the Enclave gone, the wasteland is free to build, though not to forget.

The Enclave's plan is a genocide. This makes the enemy more menacing than the Master and gives the final battle moral weight. Frank Horrigan is a strong enemy and a symbol of the Enclave's power. The oil rig's destruction is the end of the Enclave as a power in the West.

In this chapterThe G.E.C.K. is used to create a flourishing new settlement for Arroyo and Vault 13.

With the G.E.C.K., the tribe and the vault residents create a thriving new city. The Chosen One has saved both communities and ended the Enclave's plan. The epilogue slides summarise what happened to each town, from New Reno to the NCR. The consequences of earlier choices are visible, and the player sees how a single traveller changed the region. The ending shows the results of the Chosen One's choices.

The ending is more hopeful than the first game's. Instead of being exiled, the Chosen One returns to build a home. It suggests that the wasteland can recover if people work together. The epilogue is also a bridge to the next games. The NCR grows into a regional power, the Enclave remnants survive and the ideas introduced here become the political map of New Vegas and Fallout 3.

The Chosen One becomes a founder rather than an exile, a quiet reversal of the series' bleakest idea. The epilogue slides show how each town changed according to the player's reputation. The story ends with the survival of Arroyo, and the Enclave is gone, for a time.
