IXION – Chapter-Sensitive Hidden Achievement Guide (with Spoilers)

A guide to get maximum (mostly hidden) achievements from a single playthrough, or at least with minimum save-load work.

How to Obtain Chapter-Sensitive Hidden Achievements

Prologue

You Had One Job…

  • Fail to make it past the prologue

Description: Disable (or do not build) your Mess Hall, set the game to maximum speed and wait till you fail.

Breaking Protocol

  • Discover Outer Hope during the prologue

Description: Send a probe to almost directly East (very slightly South) of Moon to discover Unauthorized Access location and complete the events (Just visiting might be enough, but the rewards are quite worth 30 Alloy during early game anyway.).

Help of the Forgotten Member

  • Implement the Naomi protocol 3 times

Description: While you are at the achievement above, choose the Naomi option to make it count towards the achievement (“Naomi Protocol: Create a temporary easement”).

Chapter 1

Access Granted

  • Use the body of Oulixes to access the Thianki

Description:

  • Do not start the Neptune event before you find and complete the Saturn event.
  • Saturn choice: Make contact > Break through the ice.
  • Neptune choice: Use Oulixes’ biometric data to open the sealed room

Help of the Forgotten Member

  • Implement the Naomi protocol 3 times

Description:

  • Discover Uranus with a probe.
  • Start the science event.
  • Choose the Naomi option (“Naomi Protocol: Cut down the tree”).

Chapter 2

Better Him Than Me

  • Replace Edden with the P.A. of the Protagoras

Description:

  • At the end of the Chapter 2 – Protagoras main quest event, choose “Naomi protocol: Save a copy of the Protagoras’ P.A.” option to be able to achieve this later.

Help of the Forgotten Member

  • Implement the Naomi protocol 3 times

Description:

  • While you are at the achievement above, choose the Naomi option to make it count towards the achievement (“Naomi Protocol: Save a copy of the Protagoras’ P.A.”).
  • During the main quest event Man is the Measure of all Things, choose the Naomi option.
  • At this point, your 3 times should be done, but some redundancies nevertheless:
  • Science Event Mack R: (“Thaw the Ice” -> “Naomi Protocol: Send a team”).
  • Science Event Tatra v8: (“Naomi Protocol: Interrogate the P.A”).

Necessary Enhancement

  • Use exoskeletons to ensure no crew members die on Fargo 39

Description:

  • Before starting the Fargo 39 science event, make sure you researched Exoskeletons upgrade in the Tech Lab under Science Ship.
  • Choose the corresponding option during the event (“Deploy the entire crew in reinforced exoskeletons.”).

Guy de Borderlands

  • Entertain your crew members

Description: This is not actually Chapter 2 specific, but probably the best time to do it here.

  • Set up an Alternative Life Center as soon as you can and this one will pop up by itself eventually.

Chapter 3

Man’s Best Friend

  • Adopt the borzoi

Description: Visit Collapsed Food District and complete the events with these choices: Investigate the Animal Pens > Naomi Protocol.

Mutual Loyalty

  • The borzoi survives the journey

Description:

  • Shortly after you adopted the Dog, the P.A. will ask you whether to exterminate it for health purposes or keep it.
  • Simply keep it and you will get the achievement when you finish the game.

Help of the Forgotten Member

  • Implement the Naomi protocol 3 times

Description: While you are at the achievement above, choose the Naomi option to make it count towards the achievement (“Naomi Protocol: Create a temporary easement”).

  • At this point, your 3 times should be done, but another redundancy nevertheless:
    • Science Event Collapsed Food District: (“Investigate the animal pens > Naomi Protocol”)

Oats

  • Free ZY6073

Description:

  • Discover Medical District Wreckage with a probe.
  • Make a manual save, because your entire crew will be killed and you will retrieve only ZY6073 and your science ship.
  • Start the science event.
  • Choose Investigate the Research Facility -> Retrieve ZY6073.
  • Get the achievement and load your save, then choose a safer option or leave.

Chapter 4

Tiqqun Contender

  • Have a member of Tiqqun compose a rap song about the Administrator

Description: This is not actually Chapter 4 specific, but probably the best time to do it in is early/mid Chapter 4.

  • In one of your sectors with Waste policy on, let two small stockpiles fill up with Waste and wait for the protest event to pop.

Catastrophe Avoided

  • Destroy the Piranesi before it destroys a planet

Description: This is a Chapter 5 achievement, but you should actually start paying attention about being well-prepared after halfway into Chapter 4.

  • You will be in a constant rush after late Chapter 4 and probably will not be able to re-establish vast supply lines and get this achievement at the same time.
  • Install one or two more EVA Airlocks for repairs.
  • Stock up on at least about 1200 Alloy.
  • You will need about 600 Colonists ready to depart or about 500 Polymer stocked depending on the ending.

Chapter 5

There are two different endings and a difficult, rushy achievement here, so make a manual save right at the beginning.

Catastrophe Avoided

  • Destroy the Piranesi before it destroys a planet

Description:

  • Whichever ending (Remus or Romulus) you choose, you need to complete the game before our old friend Piranesi reaches Remus and destroys it.
  • For both endings, you need to have 1000 tiles of Tiqqun covered with (any size of) batteries.
  • Tip: You can dismantle these back once Main Quest advances if you’re low, but you need to have 1000 cells at one point.
  • For Remus ending, you will need a new building and a 10-cycle process.
  • For Remulus ending, you will need about 600 colonists ready to depart.

In Genetic Conatus We Trust

  • Finish the game by following the path of Genetic Conatus

Description:

  • Visit Remus.
  • Meet the Ashtangites.
  • Research and build their new building.
  • Ignore the comms about Romulus planet and Edden being a liar.
  • Adapt your whole crew (10 cycles) and finish the game.

Tiqqun Unchained

  • Finish the game by emancipating yourself from DOLOS

Description:

  • Do not start the Remus event. Just go park at it and collect the science.
  • Send a probe West of the star, discover Remulus and send a Science Ship.
  • The P.A. will tell you that the crew is having hallucinations and that Remulus does not exist.
  • After a while, you will get two different communications as events in the Tiqqun.
  • Following these events, you will eventually disable your P.A. Edden and be able to interact with Remulus.
  • Follow the Remulus line to complete the game and you will get this achievement.

Better Him Than Me

  • Replace Edden with the P.A. of the Protagoras

Description:

  • Remember that we copied the Protagoras’ P.A. in Chapter 2?
  • At the very end, when you are asked to fly Tiqqun into the Piranesi, choose the “Replace Edden with Protagoras’ AI” option.

Notes

These remaining 3 of the 17 hidden achievements are those I’ve neither figured out, nor could find any info about. They may be a) WIP, b) well hidden, c) deeply connected to eachother somehow or d) bugged for the time being, I just don’t know.

What They Hide From Us

  • Discover the ruins of the genetic facility
  • Chapter: Unknown

I’ve tried scouting the locations instead of doing “the obvious objective” (avoiding too much spoilers) in Chapter 5, but no luck (Surprise: Those choices all destroy the ship and kill all the crew!).

Delivery!

  • Research every single upgrade for the Drone Bay
  • Chapter: 4+

I’ve completed every upgrade for the Drone Bay, but it did not unlock. Might be just bugged, or we might need to have found a Science Ship choice type of hidden upgrade for this earlier, which so far no one did apparently.

Beyond Time and Space

  • Finish the chain of events concerning the strange spheres
  • Chapter: Unknown, most likely 2+

Again, no further info or achievers yet. It is believed to start with Rockatansky D79 sphere, which needs Science Ship – Deep Dive Apparatus upgrade to fully complete, but I don’t have positive confirmation.
