100% Achievement Guide

Some of the achievements for the game aren't very clear on how you are supposed to do them, which is why I am writing this guide.

I'm gonna be brutally honest with anyone who reads this. Quite a few of the achievements in this guide need to either be coded better or worded better because there are a few where you actually need to decipher how they want you to do them. They are either convoluted or entirely misleading. In this guide, I will be doing my best to help. However, there are a couple on here that really stick out to me as they are achievements I should have but I don't because of how unclear the achievement descriptions are. There are also some I would've honestly had gotten sooner if the descriptions were more helpful.

With that said, I’d like to give a big thanks to kenny and Babda for their comments, as they've made this more accurate.

Story

Location Achievements:

These are fairly self-explanatory but this is a 100% guide.

Ready to Move On?

Complete Retrieve the Ironheart operation and return to Albion

This Achievement is received when you have finished the tutorial.

First Sweep Operation

Complete all available missions and Descendant duties in Kingston

This Achievement is received when you complete every story required mission in Kingston.

Hope Within the Dust

Complete all available missions and Descendant Duties in The Sterile Land

This Achievement is received when you complete every story required mission in The Sterile Land.

Knock, Knock! Who is it?

Complete all available missions and Descendant Duties in Vespers

This Achievement is received when you complete every story required mission in Vespers.

Quest Related:

These are quest-related achievements you will complete while doing the story.

Pre-emptive Strike for the Future

Complete a Void Intercept Battle for the first time

As part of the story, after returning to Albion and talking to the Guide after finishing the Kingston area, the Grave Walker appears in the Void. You are then given a quest to speak to Seneca who explains what is going on. All you gotta do is kill the Grave Walker and you get this achievement.

The Sensible Life of Research

Complete research for the first time

As part of the story, you will need to build Bunny from the materials you got from the Kingston area and Grave Walker (one of the Amorphous Materials you get from a mission in Kingston is a guaranteed Bunny Blueprint drop). If you haven't already visited Anais, then this is likely how you'll get this achievement.

No Hope for the Vulgus

Obtain an Ultimate tier weapon

The first Ultimate weapon you'll craft will be Thunder Cage as part of a quest for the weapon.

Advancement

Advancement Achievements:

These are just achievements you'll get for playing, and strengthening your Descendant or Weapons. Some of these may be quest related, but you'll likely do some of them before the Descendant Trainer gives you the Side Quest related to them.

Is This How You Insert it?

Equip a module for the first time

Just equip a module on any weapon or Descendant you have.

Ready, Extract, Complete

Level up a weapon through Weapon Transmission

Go to a Workbench (look for the Wrench/Cogwheel icon). You will need a higher level weapon compared to what you currently have equipped and, depending on the rarity, you will either need 1-4 Phase Exchangers (Common and Rare Weapons) or 1 Precision Phase Exchanger (Ultimate Weapons).

What Was Always Expected

Reach Level 40 with any Descendant

Honestly will just happen as you play the game. You'll get this faster if you just stick with your original Descendant until you get this achievement.

Growing Possibility

Enhance a weapon's Unique Ability for the first time

Works with Ultimate weapons but you'll need the same weapon to do this. The first time you'll do this is with the Thunder Cage.

This Is Great, Sevenfold

Enhance any module to +7

Will take some Kuiper grinding but you'll want to talk to Silion and rank up a module seven times. I recommend doing a Sub Module like Shock Punch first as Sub Modules increase your Descendant's mod capacity.

Power! O, Infinite Power!

Reach Mastery Rank 10

You'll eventually reach this as you continue playing.

Modules Maketh Descendant

Expand a Descendant's Module Capacity

You'll need an Energy Activator. You get your first one upon a Descendant reaching Level 40 and talking to the Descendant Trainer.

This Reaction's a First

Enhance a Reactor for the first time

You will need Ion Accelerators (Rare Reactors) or two Precise Ion Accelerators (Ultimate Reactors). I've never enhanced a Rare Reactor before so I can't tell you how many Ion Accelerators you'll need but, as you'll likely be fighting Colossi, I recommend sticking to the Ultimate Reactors for the most part.

Place for Something Special

Expand the module capacity of a weapon that uses Special Rounds

Same thing as the Modules Maketh Descendant Achievement. You will of course need to farm for the materials you'll need for the Energy Activator.

Slot Maketh Module

Assign module socket types 10 times

This one will be a pain in the ass as you'll need to get the materials for and craft 10 Crystallization Catalysts. (This has been fixed. Originally it needed to be done in one session but a hotfix on July 24th seems to have fixed that)

Miscellaneous

Miscellaneous Achievements:

These are achievements that I couldn't really fit in either of the other categories

Out of Weapons

Dismantle weapons 50 times

This is the first of several in this section where the instructions aren't all that clear. You would think it can be done in stages but it can't. For this achievement, you have to dismantle 50 weapons all at once which, in my opinion, isn't fair. Especially for the players who are big into inventory management.

Special Operation Task Squad

Clear up to Wave 7 in the Kingston Albion Resource Defense mission

As long as you don't fail, you will get this the first time you do that mission and I highly recommend it as it has very useful items to farm for.

Good Things Happen Twice

Successfully remove Colossi parts 2 times (excluding Retrieve the Ironheart operation)

You have to hook onto a removable part if its glowing yellow, and beat the ♥♥♥♥ outta it. For this, I recommend running a private intercept against the Grave Walker as that will be the easiest Colossi to defeat. It will also prevent anyone else from resetting your progress for this achievement.

Execute Order 77

Dismantle modules 77 times

Just farming a lot and go to Silion to dismantle dupes or anything you don't want. This one will have to be done all at once as I've dismantled about 2000 of them, according to the game, but haven't gotten the achievement yet.

Descendants, Assemble

Own 5 Descendants

This is rather easy as you can get them all for free and, not including the one you chose when starting the game, your first two are actually sub-quests. Bunny can be built upon completing Kingston while Freyna can be built after Vespers or halfway into Echo Swamp. I'm currently almost done farming my fourth Descendant: Valby.

I Can See the Future of the Colossi

Complete 10 Void Intercept Battles

This one you should get relatively easily as you need to fight Colossi a lot to open Amorphous Material Patterns to get materials for various things like Descendants and Ultimate tier weapons.

And Combining, to Boot

Combine modules 7 times

For this one, you'll likely need to do them in one go as I never got it in the two-stage attempt I made to get this achievement.

[Razorkiller]

Got it, thanks again for the guide. 100%-ed the game.

[Razorkiller]

This is still by far the dumbest prestige achievement I had to obtain.

[Razorkiller]

No so my bad on the end, I didn't notice till now.
Challenge says that I applied 8 socket modules. Meaning by default Descendants / Weapons can have already assigned socket modules. Plus challenges keep track. I need 2 more. I'll update once I do more grind later on and have spare Catalysts to prepare.
So if anybody is confused why they didn't have them yet then now you know. (Just count freshly and ignore the already applied sockets which is still weird they don't apply as a whole but whatever)

[Natsu Cadogan]

I was afraid of that because I was about to say it either needed to be on one weapon, spread between items, or an update broke the achievement again. Back in July, one of the comments kenny posted mentioned the hotfix that led to the achievement being fixed. If it's fucked again... I honestly have no words because the grind is already painful.

[Razorkiller]

So, I'm doing background research and it seems even after people doing this more than 10 times.
It still doesn't unlock. Some folks are suggesting regardless you do this in multiple sessions, you need to do this in one go. Even though hotfix is applied I don't know why I didn't get it for its instance.

[Natsu Cadogan]

It's 10 Crystallization Catalysts, not the mods, Razor. You need to use the Catalysts to assign module sockets to items or Descendants. If you've played Warframe, it is kinda like installing Forma on a weapon or Warframe. Each assigned socket halves the drain of a module that matches that socket type.

I hope this helps, I'm honestly not good at explaining things.

[Razorkiller]

I need clarification. Slot Maketh Module achievement? I placed 10 modules for the Descendant.
I didn't get the achievement. Was this meant to be done for items and not for Descendant? Or am I missing something?

[Razorkiller]

Huge thanks for clarifying last of the achievements. Helped a lot.
Some of these achievement descriptions are too vague and give small clues. But managed to speed up my last things and almost done with them too!

[Natsu Cadogan]

Thanks, kenny. Just updated the guide with the new information.

[ws]

I Can See the Future of the Colossi has been fixed as well. You don't need to do it in the same conditions. My friend just got the achievement after clearing hard mode Pyromaniac and he's never fought the same boss more than once.
