Girl Genius Adventures In Castle Heterodyne 100% Achievements Guide

Here’s a guide on how to unlock all the achievements in the game without revealing any story spoilers or significant gameplay secrets. It’s important to note that if you’re aiming for a single playthrough to obtain all achievements, there’s one specific achievement called “Doing it the Hard Way” that you must not miss. It becomes unattainable after a certain story point, which occurs after acquiring the boom bot. Additionally, there are several achievements tied to the difficulty level you select, so it’s advisable to play on the hard difficulty setting if you intend to complete all achievements in a single save file.

General Tips

Here are some general tips to keep in mind as you pursue all the achievements in the game:

• Enemy Respawns: It’s important to know that enemies will respawn when you close and reopen the game. However, they won’t respawn if you simply reload the game without closing it, whether you do it through the in-game menu or due to character death.
• Progress and Saves: Be aware that loot, in-game achievements, defeated enemies, and other similar progress elements do not save separately within the game. In other words, if you acquire loot, unlock achievements, defeat enemies, solve puzzles, or achieve any in-game milestones, and then you die or reload the game before it has a chance to save, you will lose all that progress. This means you’ll lose the achievements, loot, and the enemies will reappear.

If you have additional tips to contribute to this guide, please feel free to share them in the comments section. These insights can be invaluable for fellow gamers aiming to complete all the achievements without any major setbacks.

Difficulty Achievements

There are three achievements tied to beating the game on a certain difficulty.

• Heterodyne – story/easy mode
• True Heterodyne – normal mode
• Terror of Mechanicsburg – hard mode

It’s essential to keep in mind that for the normal and hard difficulty achievements, you cannot lower the difficulty setting at any point during your playthrough. Specifically, if you initiate the game on hard difficulty, you’ll only earn the “Terror of Mechanicsburg” achievement if you maintain the same difficulty setting throughout the entire game without any changes.

Moreover, there’s a noteworthy benefit when you complete the game on a higher difficulty setting. By doing so, you automatically unlock the achievements for completing the game on lower difficulty levels as well. For instance, finishing the game on normal mode will grant you both the “True Heterodyne” and “Heterodyne” achievements, while completing it on hard mode will earn you all three achievements related to difficulty settings.

Story Achievements

Achievements which are tied to story progression, and as a result anyone who beats the game will obtain.

• A Quest For A Glorious Cup Of Coffee
• Spark Moment
• The Blood is the Key
• Hey! Listen!
• Giver of Life
• Schools Out!
• The Gang Is Assembled
• Pinkie’s Last Flight

After finishing the game, if you are missing any of these accomplishments, there was a glitch, and you may need to start over with a fresh file.

General Combat Achievements

Obtaining achievements that need killing a specific enemy type in a set number of battles. While many of these may probably be acquired by simply playing the game normally through to the end, if you’ve already done so and are missing any of these, the spoilers will tell you how to acquire them.

• Baw-kah-BOOM! – Destroy 25 Chicken Clanks. Go to The Arena and complete the Baw-Kah-BOOM! challenge a few times.
• Not on-the-fence – Destroy 15 Fencing Clanks. Go to The Arena and complete the Fencing Clank Troupe challenge.
• Martial Demotions! – Destroy 5 Fencing Clank Captains. Go to The Arena and complete the Captain’s Cartel challenge a couple times. Alternatively, since that challenge only has 1 captain so it can be a little slow, you can go to the Herbatorium Entrance (very near the end of the game) and going to the Herbatorium Hallway, killing every captain in both rooms.
• In need of support! – Destroy a Shield Clank that is currently shielding 3 or more enemies. Go to The Arena and complete the Battery of Shields challenge.
• EEEK! – Destroy 5 Nyar Spiders. Nyar Spiders are killed by drilling into soft ground as the dingbot and coming out underneath the spider. There is, to my knowledge, only one place in the game with two Nyar spiders together, near Sgt. Clumsy. If you don’t mind spoilers for that particular collectible, open the next spoiler. Otherwise, there are Nyar spiders in the dingbot sections of The Foundry, which is to the left of The Arena. in the TGMC Well Shrine room, in a slightly hidden area behind a short wall in the flying area.

Loot (Money) Achievements

You need loot to upgrade your tools and make coffee (I also put 20 pieces of scrap metal into my coffee maker every morning to make my cup of joe), which is required for three achievements. Each sort of loot is more rare than the previous one. There are three different kinds of loot: white (scrap), green (mechanical parts), and blue (wild inventions). To improve everything and obtain all of the achievements listed below, you will require a lot of each of the three categories.

• Scrap Collector – Find a total of 777 resources.
• Glorious Coffee – Upgraded the Coffee Machine to its highest tier. (when interacting with the coffee machine only in The Hub, you can upgrade it to increase the health per use and amount of uses your coffee provides. You cannot upgrade it outside of the hub.)
• Modular Marvel – Build all modules for your weapons and tools to their highest tier. (This requires getting every blueprint- see the Collectible Achievements section for more.)

If you are struggling to afford everything, there are four ways to get more loot:

1. Completing the arena challenges. This will only award loot on the first completion of each challenge, and enemies in the arena don’t drop loot.
2. Opening secret loot chests scattered around the world. These include both the chests you open as Agatha and those you open as dingbot. Make sure to look around in every nook and cranny for them!
3. Lockpicking dingbot locks without making a single mistake. This rewards you with bonus loot.
4. Destroying enemies and boxes. This is the only renewable source of loot, as every other way to get any locks you from getting more loot from its source after you get it once. However, because enemies and boxes are capable of respawning, this is a way to get infinite loot, even if it is fairly slow.

Collectible Achievements

These accomplishments depend on discovering optional mysteries around the globe.

Huge thanks to them because this list solely relies on this collectibles guide! If you’re having trouble getting any of these achievements, just utilize their guide:

• Art Connoisseur – Find all the portraits.
• Dingbot Supreme – Find all the dingbot sergeants.
• Self Improvement – Find all Heterodyne Artifacts.
• Master of the Arena – Defeat all the challenges with a Mastery Badge in the Arena. (Even though the accomplishment doesn’t really fit in this category, I’m including it here because it is also for an artifact and you should consider these suggestions if you plan to attempt it. This calls for completing each test within the allotted time frame and without suffering any damage. You don’t have to do both at once; you can complete the low time run and no-damage run separately, and it will still contribute toward the mastery badge.)
• Loremaster – Find all Lore Segments.

However, there are some things the guide does not mention:

• Recipes for Disaster – Find every tool upgrade blueprint. guide TBA
• Chronomoira – Find Chronomoira the Clank. In The Foundry, which is to the left of The Arena, there are a bunch of dingbot sections scattered throughout. Completing all of them opens a door (next to which there is a sign that says “good luck opening this door. we’ve tried for years.” Chronomoira is past the door.)
• Queen of the Castle – 100% completion. (get every collectible and upgrade every tool to the max. Unsure if Chronomoira’s shop is included in this.)

Miscellaneous Achievements

These Achievements don’t fit neatly into any category. Many of these are hard to get unless you’re specifically looking to get every achievement.

• Doing it the Hard Way – Find the “Mirror Shard” Artifact before building the Boom Clank on the Workbench. Feel free to refer to this guide if you need more help.
• Three Stones, one Bird – Launch a Chicken Clank by hitting it with the Wrench, and the explosion destroys 3 or more enemies. I recommend doing this achievement and the Chain Reaction achievement at the same time. Simply go to the Baw-Kah-BOOM! Challenge in The Arena and use the many chicken clanks in round 3 to blow each other up.
• Take the Shot! – Destroy 4 or more enemies with one Deathray blast. Simply go into any challenge in The Arena with a lot of enemies, such as Fencing Clank Troupe, and use a deathray blast during the third round. Don’t worry if you mess up, your spark meter recharges every time you start a challenge.
• They see me Rollin’ – Destroy an enemy with a moving Rollerclank. I recommend using the Corridor of Portraits room, which is to the right of The Grand Gallery.
• Chain Reaction – Hit a Chicken Clank with the Wrench that results in a chain explosion of 3 or more Chicken Clanks. I recommend doing this achievement and the Three Stones, One Bird achievement at the same time. Simply go to the Baw-Kah-BOOM! Challenge in The Arena and use the many chicken clanks in round 3 to blow each other up.
• A Perfect Moment In Time – Command the Castle to destroy 3 or more enemies with a single trap. Go to the Corridor of Portraits room, which is to the right of The Grand Gallery, and bait as many fencing clanks to chase you around so you can line up a trap to crush as many as possible. I recommend destroying the Sting-rays before baiting the fencing clanks as those are much harder to bait.
