Siding with Foundation

Siding with Foundation is a main quest in the Fallout 76 update Wastelanders.

Walkthrough
Talk with Paige to confirm the choice to side with Foundation for the heist on Vault 79. This immediately completes the quest. Before making their decision, a message box will appear to warn the player, that their decision is final, giving them time to reconsider or back out for the time being before making up their mind.

Confirming the choice to aid the Settlers leads to the Division of Wealth quest. Note that any active quests from the Crater Raider quest line are automatically failed and access to potential follow-up quests is void. These include Cheating Death, Fun and Games, The Ol' Weston Shuffle, Siding with Crater, From Russia With Lev and Buried Treasure.
