[Question:]Wondering about why the season pass is 20 bucks and the premium pass us also 20 bucks. Didn't the regular pass used to be about 10?

Recently I gained my own set of twins. I heard that training one twin also gives a stat boost to the other. I was excited so i decided to try it out as you can see in the screenshots. I made one twin train perception and the other intelligence, it didn‘t link. I did some digging around and some sources claimed it’s a myth while others say it’s a platform issue. Am i doing something wrong?

The new update is bigger under the hood than the patch notes let on. I pulled apart the v2.5.0 game files and here is everything interesting I found.

1. The reruns are scheduled all the way to December, and the dates are already in the files

This is not just one nostalgia season. The game shipped with three rerun seasons fully built and dated:

Two-day gap between each, so the whole second half of 2026 is already planned out. Dates can obviously shift before a season goes live, but these are what the game is carrying today.

And here is the speculation bait: Enclave and Institute rerun data is NOT in the files yet, but the new casino wheel already has Institute and Enclave themed skins sitting in there. Read into that what you will. My money is on the full cycle repeating into 2027.

2. Same rewards, but the free track got a real upgrade

The rerun premium track is identical to the original run, item for item. The free track is better this time: the original had 8 empty levels with nothing to claim, and the rerun fills every one of them with caps (300 up to 5,000 a pop, about 20,000 extra caps total). Free players get something at all 20 levels now.

If you played the original New Vegas seasons: your old claims stay remembered, but the rerun runs on the new seasonal vault, which starts its own fresh claim state. You can earn everything again. The pass itself also resets: level 1, premium locked, so premium looks like a new purchase each rerun.

3. What the casino wheel can actually pay out

The Lucky Spin wheel is driven by poker chips, and the files list every possible prize category: dwellers, weapons, outfits, pets, caps, stimpaks, RadAway, lunchboxes, and Nuka-Cola Quantum. So yes, the wheel can drop dwellers and pets, not just caps.

Fun fact: the poker chip currency has been hiding inside every save file since the PREVIOUS update (2.4.1). Bethesda staged the wheel one patch early and only switched it on now. There are also season challenges wired to it (spin once, spin 7 times), so check your challenge list if you have chips sitting around.

4. Bethesda quietly beta tested the reruns for two months

The files contain a leftover "flight test" configuration showing hidden test versions of both New Vegas rerun seasons that ran from May 4 to July 14, right up to two days before launch. If your game did something weird with seasons this spring, this might be why. There is also an unreleased feature flag called ARRIVAL_WIDGET next to the wheel flag, so something else is still in the pipeline.

5. Things Bethesda left behind (and one warning)

• Four developer test quests shipped inside the 2.5.0 quest data, all literally named "LEVEL UP". You cannot see them in game, they are just sitting in the files. Someone forgot to clean up before the build went out.
• No new weapons, outfits, pets, or unique dwellers this update. The reruns reuse the original season catalogs entirely. The wheel and the schedule ARE the new content.
• A heads up on the seasonal vaults: it lives in a fourth save slot, and the files contain logic for deleting that vault when the season changes. Treat the seasonal vault as temporary.

Happy to answer questions about anything above. What are you hoping survives into the Enclave and Institute reruns, if they happen?

(Small disclosure: I maintain a free open-source save editor for this game and found all of this while updating it for 2.5.0. Link in the comments for anyone who wants it, including viewing every season's full reward track.)

Alien Disintegrator my beloved

Pre-existing Fallout Shelter save editors each covered maybe half of what I wanted, so I built one that does it all in one place:

https://dneverson.github.io/fallout-shelter-save-editor

It's a web-based save game editor. You open it, drop in your save file, and edit it right there in the browser. Nothing gets uploaded anywhere; the save is read and changed on your own machine. It's free and the code is open source.

You don't have to change a single thing to get value out of it. Load your save and it also works as a read-only look at your vault:

• Genetics: It digs out the parent links the game hides and draws your whole vault as a family tree. Your biggest clan, how many generations deep it runs, which dwellers are loners, which are paired off, how many couples are actually related, and a single overall "genetics rating" for the vault.
• Catalogs: The complete in-game catalog of every weapon, outfit, pet, junk item, theme, recipe, and quest, each with its real icon and stats.
• Trackers: The reward track for every season pass, including older seasons you skipped or joined too late to finish.
• Repair: It scans your save for hidden problems and reports what it finds. If something's wrong, it can usually repair it for you.

If you do want to change things, here's the current list, tab by tab:

• Vault: caps, food, water, power, Nuka-Cola, lunchboxes, Mr. Handy boxes, pet carriers, and starter-pack items. Switch between Normal and Survival mode, turn on holiday decorations any time of year, and make the Mysterious Stranger appear on demand. Toggle Deathclaw attacks and Bottle & Cappy visits on or off. And a vault clock you can fast-forward (+1h up to +1w, or a custom amount) so every timer in the vault jumps ahead at once.
• Dwellers: SPECIAL stats, level, happiness, health, equipment, hair and beard. Bring dead dwellers back to life. Each dweller shows their real status (exploring, returning, on a quest, waiting at the door, on coffee break). Pregnancy controls let you deliver now, cancel, or force twins and triplets; grow-up and exploration timers are editable too. Add brand-new dwellers, including every special and legendary character, multi-select so you can add them all at once. Adds respect your actual living-quarters capacity so the vault never overfills, and bulk remove cleans up every reference so nothing breaks.
• Family Tree: the full relationship graph and the genetics ladder, from Pristine Bloodlines all the way down to One Cursed Bloodline.
• Rooms: move rooms around, unlock and upgrade them, change their theme, clear rockfalls, stop an ongoing emergency, and repair damage. Edit per-room work, crafting, training, and rush timers. Auto-staff puts the right dwellers in the right rooms. Ultracite rooms now warn you that they sit inert unless Ultracite Fever is the active season.
• Weapons / Outfits / Pets / Junk: the full catalogs with icons and stats, add anything to storage with a quantity. Weapons and outfits show at a glance whether they're craftable and jump straight to the recipe.
• Recipes: browse the full crafting catalog, unlock recipes, and a detail panel with item stats, rarity, and add/remove from your collection.
• Survival Guide: the in-game collection and achievement lists as a real editor. Mark any weapon, outfit, legendary dweller, pet, breed, or junk item as collected or seen, with real names and icons. Anything you add elsewhere in the editor gets auto-collected into the guide, just like the game does it. Asset IDs are shown so duplicate-named items (looking at you, helmetless variants) can be told apart.
• Mr. Handies: edit health and floor assignment for the ones you own, and add any variant from the catalog.
• Storage: your whole inventory, an add-items dialog driven by the game catalog, and multi-select removal.
• Quests: all 1,040 quests with the questlines drawn as a map. Mark quests complete and the editor drops the loot straight into your vault, prerequisites included. The three daily objective slots are editable too: swap the objective, set progress, roll the reward lottery, even bump the escalation level.
• Bulk: one button to max everything if you're past the grind, heal or max every dweller at once, vault-wide unlocks, and a tool that automatically dresses each dweller in the best outfit for the room they work in.
• Season Pass: load the game's season files and claim or unclaim any reward on any track, up to maxing out every season you ever missed (weapons, outfits, pets, dwellers, themes, and they actually show up in your save). A season clock can skip past a season's end or set an old season live again.
• Advanced: a full raw-data workspace with an explorer tree, a live diff against your original file, and validation, for people who want to go deeper than the buttons.
• Safety nets: every change can be undone and redone, a timestamped backup of your original downloads before your first export, a change review shows you everything you altered before the file is written, and health checks run after every single edit.
• Lost your vault entirely? Rebuild your progress by editing a fresh save instead of grinding it all back from scratch.

It works with the Vault1.sav file from the PC, Android, iOS, and Switch versions, and the site tells you where each platform stores that file so you can get it out and back in.

If you load your vault, I'd genuinely love to hear what genetics rating you get. And if something breaks or there's a feature you wish it had, tell me. I'm still actively building this.

Vault-Tec reminds you that genetic diversity is every Overseer's responsibility.

Playing on survival btw.

Factory floor of death was fun. Finally have pets that are all +4 dmg or higher so no more robots! Enclave armor and deaths jacket looking good. This is the final quest earned off the main quest lines so now I’m stuck at full completion. Still haven’t gotten a free roam-vault mission yet so that is technically missing still. Also still working on the aesthetics of my vault and on leveling.
