Bethesda’s Gone Fission expansion, a free update for Fallout 76, launched on June 3, 2025, bringing one of the franchise’s most longstanding player requests to life: fishing. But beyond casting lines into irradiated streams, Gone Fission delivers a buffet of gameplay enhancements—from deep combat rebalances to seasonal progression and quality-of-life upgrades. Here’s an in-depth look at what is in this expansion pack and why it matters.
Gone Fission’s center stage is the new Fishing mechanic: players embark on the “Casting Off” questline in a newly introduced locale, Fisherman’s Rest, in The Mire fallout. Here you meet characters like Captain Raymond Clark, The Fisherman, and a pet hermit crab named Linda‑Lee. They gift you your first Fishing Rod, which isn’t equipable—instead, simply stand near any swimmable water to trigger a “Fish” prompt.
Just like a real angler, you’ll need the right gear and ingredients. Rod upgrades—including new reels and bobbers—come from completing fishing-specific challenges and daily quests. Meanwhile, you’ll source bait from multiple avenues: Common Bait (vended or quest-earned), Improved Bait (loot/trades), and Superb Bait (exclusive Season 21 rewards). A dynamic interplay of bait type and weather conditions determines the fish you attract—clear weather yields typical catches, rain boosts regional fish and monthly Axolotls, while radstorms increase your odds of landing glowing fish.
Per enthusiast community reports, “Anywhere you can swim, you can fish”. It’s a wonderfully simple system that adds depth without clutter.
Once hooked, fish have multiple uses:
Consume them to restore health and hunger.
Use daily fish quests to unlock hearty recipes like Fish & Tatos and Fish Chowder.
Trade Fish Bits with Linda‑Lee to earn legendary items.
Flaunt your trophies—common, axolotl, glowing, or “Local Legends”—in your C.A.M.P. with new display items awarded from challenges.
Gone Fission injects that satisfying gameplay loop: catch, cook, buff, and showcase.
Gone Fission marks the start of Season 21, filled with fishing-themed rewards. As part of the new season track, players can unlock cosmetic gear, Camp items, bait, and premium Superb Bait—all fish-related.
To support loyalty, unused Season Tickets from the past three seasons are automatically converted to Gold Bullion—a catch-up mechanic for latecomers.
While Gone Fission’s headline is fishing, Bethesda leveraged the expansion to deliver a significant combat overhaul. Highlights include:
Damage increases across rifles, SMGs, melee weapons, and over 50 different weapon types.
Shift to consistent limb-damage effects: more predictable crippling instead of random chance.
Buffs to perks and Legendary mods, streamlining power builds and utility.
Removal of crafting depot antics: no longer requiring perk cards to build weapons or traps.
A slew of quality-of-life fixes across areas, enemies, and UI.
PC Gamer summed it up: “Gone Fission does more than let you yoink marine life … it also brings a significant overhaul to the game’s combat.”
Gone Fission is sizeable:
PC (Steam): ~15 GB
PC (Microsoft Store): ~32.5 GB
Xbox: ~32.6 GB
PlayStation: ~8.2 GB
The update drops globally on PC, Xbox One/Series X|S, and PlayStation 4/5 .
Despite Fallout 76’s rocky launch in 2018, this update signals a continued shift toward engaging content and systemic refinement.
Reddit buzz: “The irradiated Appalachian waters now play host to a variety of different fish … Put on your most comfortable outfit and … fish.”
PC Gamer praised the punny title as a gateway to a meaty combat update.
Shortlist noted the trailer’s tone: “cosier side of Appalachia … different bait, weather conditions, rods, and locations.”
Gone Fission shows Bethesda’s attention to both novelty and gameplay depth, striking a balance between leisurely additions and long-term investment. If you’ve been waiting for Fallout’s version of a photo moment by a decrepit creek, or you just want a meatier combat stance, Gone Fission delivers both. Dive in—there’s plenty to catch.
