Summary

As one would expect, an open-world RPG game series would provide a tough challenge when going for 100 percent. TheFallouttitles are big, long, and have multiple branching paths. For certain games, you must save before key decisions, so you go back and pick something else.

Each game will take close to 100 hours to complete, and that’s not even counting the DLC. Then, there’s Fallout 76, a live-service title, and while it’s not as bad as100 percenting Grand Theft Auto Online, it’s far from a walk in the park.

Almost all of these games will be judged by the difficulty of getting not only the platinum but every DLC achievement as well. For older games, 100 percent will mean completing every quest available.

Both Easier And Harder Than The Modern Titles

With no achievements tied to Fallout 2, 100 percenting it has its advantages and disadvantages in terms of difficulty. Fallout 2 has amuch bigger game map, with a ton of quests that will require multiple playthroughs or reloading an early save.

Seeing everything this game has to offer will take a lot of time, but on the bright side, you don’t have to do the various busywork achievements forced upon you. No need to get max level, get all the weapons, or beat the game on Hard. You’ll still need to experience all the branching paths akin to New Vegas, and with the all quests time sink, it evens out in the end.

The Karma System Ruins Everything

Fallout 3 has a pretty standard achievement list, especially when looking at the DLC. You’ll need to complete all the most important side quests for achievements, more so than New Vegas, as well as craft all custom weapons. The rest are simple enough, except for a nasty batch of achievements that will really anger you if you don’t plan accordingly.

Fallout 3 has a karma system, and you’ll have to reach levels eight, 14, 20, and 30 with good, neutral, and bad karma for 12 total achievements. Naturally, many people will save before one of those milestones and try to get a different karma. The problem is that going from good to bad karma takes a while, and if you save too late, you’ve screwed yourself.

The Hardest Single-Player Fallout

Out of all the single-player Fallout games, New Vegas is by far the hardest for many reasons. First, you’ll have to beat every variation of the final mission, essentially forcing you to go through all the branching paths. You’ll also need to beat Hardcore mode, which is brutal the first time you play it.

The DLC weapons needed for challenges are wildly expensive, but the one aspect that people struggle with the most is Caravan. It’s a bad sign when youfollow a guideand start taking notes because one sentence alone has so many things going on that it just confuses your brain. That’s how intricate Caravan is.

A Long Grind

Every Fallout game takes at least 100 hours to fully complete, but no other title feels longer than Fallout Shelter. Originally a mobile game, then ported to home consoles, Fallout Shelter isn’t a fun experience to 100 percent. The achievement list feels like busy work, with most of it consisting of doing a task X number of times.

The hardest achievement has to be the one for collecting 20 legendary dwellers, which are random drops in Lunchboxes. You’ll have to get hundreds of them to reach that 20 milestone. At least there are only 35 achievements, the only bright spot here.

Building Troubles

For the most part, Fallout 4 has the easiest achievement list in the series, but there area few annoying elements. The most obvious one is the Benevolent Leader achievement, which everyone hates. Getting 100 happiness takes a ridiculous amount of time and is quite boring.

The second annoying element has to be all the building achievements, which make up two entire DLC packs. Many who don’t like the building system of Fallout 4 will likely ignore those six achievements, but they are required for the full 100 percent completion. The one involving five simultaneously tamed creatures in a settlement is especially frustrating because they often go wild when close to another creature.

The Longest And Toughest Fallout To Date

Just like how GTA and Elder Scrolls Online are the hardest games in their series, the same applies to Fallout 76. The time sink here is in a completely different league than all the other games. You’ll have to complete the main story quests as well as the DLC ones, which are usual in a game like this.

What’s also usual in a live-service game is an achievement for getting to level 100. Like with GTA, there’s ways to level up faster, but for the average person, it could take months. There’s also DLC achievements for killing enemies with specific weapons that can be a real pain to get, like the Auto Axe, or require plans that could tempt you to buy a bundle just to get it over with.
