Fallout 4 is Bethesda's open-world action RPG set in a post-nuclear Boston (the Commonwealth) where you emerge from a cryogenic vault 210 years after the Great War to find your kidnapped son. The game features an extensive perk system, base-building settlements, companion relationships, and four faction endings that dramatically alter the Commonwealth. With its modding community and ongoing DLC content (Far Harbor and Nuka-World), Fallout 4 offers hundreds of hours of exploration and combat.
Picking the right build determines how your experience plays out. These builds are ranked by overall effectiveness — factoring in damage, survivability, gear requirements, and how well they scale into endgame.
