Claim Free V-Bucks: A Quick Guide
Save the World is the original single-player campaign that Fortnite was created as a spin-off from. It is a co-op game which requires a lot of grinding for various items such as V-Bucks, which is why YouTubers like SaveTheWorld frequently run giveaways for them. There are things the game has in order to teach you how to get free V-Bucks, but only a few select in-game activities actually give you free V-Bucks:
Early on, these challenges can be tough to repeat multiple times. As you progress through the main plot, fresh tasks replace the old ones. Eventually, the well of fresh challenges runs dry, and your V-Buck grind slows or stops.
The Side Quests are to gather Shielder data, complete Storm Shield Defenses level 10, and revisit every area one last time. Each zone (Stonewood, Plankerton, Canny Valley, Twine Peaks) concludes after six defenses, leaving behind one five-star shield in each.
Below is a list of Fortnite V-Bucks challenges sorted from highest to lowest reward. Each has 20 stages, with later ones requiring more effort:
From these Save the World tasks alone, you can accumulate approximately 2,600 V-Bucks after a few months. There are also other quests like Eldritch Abominations, which reward an Active Powercell for eliminating Mist Monsters, and Leave No One Behind, which grants 10 Bacon and generous Survivor XP for saving survivors.
