No Fail / Speedrun Achievements
There are achievements influenced by your performance during the game, like speedrun one, or to not fail any puzzle.

Here is the good news about them:

While it is easy to die, fail on puzzles, and while there are no manual saves, no save file to back up, you can still fail. Just push alt+f4 when that happens and restart the game from previous save location. I failed on all: The Witch, East Ocean Noble, Flawless Memory and still managed to get them on my second walkthrough with this method.

In a Flash
Complete the game in 8 hours



Get from start to end in 8hours (playtime). This is something you shouldn't get during your first playthrough, if you did, then you skipped the whole story and shame on you:-)

Flawless Memory
Complete the game without failing once



Because of random dice rolls it is easy to die and you can't do anything about it. So whenever that happens just alt+f4 before the screen goes back to the Old Jun and restart the game and continue from the previous checkpoints.

East Ocean Noble
Complete all the East Ocean puzzles without any mistakes



East Oceas puzzles are like the ones on the following picture. If you fail once just alt+f4 and continue from previous checkpoint.

The Witch
Complete the game without resonating with the wrong starsong



Same like before, if you failed any, just alt+f4 and continue from previous checkpoint. Starsong puzzles are these:


ALL THE ABOVE UNLOCKS AFTER THE CREDITS DONE, SO DON'T PANIC WHEN NONE UNLOCKED AT THE ACTUAL END OF THE GAME
Misc achievements
These achievements could be earned any time and not related to any chapter.

Fuel Monster
Completely run out of fuel twice



Run out of fuel twice in a single game. Nope, it is not enough to reach zero. If you have 2 fuel select a destination which require 3+ fuels and confirm that you will travel anyway. This action isn't count as death as rescue ship will arrive.

Red Chamber, my precious!
Fully deck out Red Chamber



Fully upgrade a ship. Getting the materials for it will be easy, you will have issues with only one upgrade as it unlocks during chapter 3 or 4 and the required material for it could be found at a chapter 2 location and it is unlikely anyone ever revisited that location. Explore for the broken communication modules at the location: Trading Post: Mayfair, which is the same where you could get the achievement "remember her generousity" during chapter 2.

There's always a story to tell if you fail
Acquire over 3 Tales of Failure



Fail rolls during events multiple times to get 3 of these items. It is not awarded all the time, but in a regular playthrough, without reloading last checkpoints, it is unlikely that you will end up without this achievement.

Memories: Items of the Peak, Part 2 lists a few places where you can find this item, and at least 3 of them don't reward any other missable memory, so safe to take them.

Thought I was dead
Die twice in a playthrough



Die twice, which is quite easy, you need to get to the screen with the Old Jun to get a death to registered. First time you can do this while you earning the "I'm not afraid" achievement in the first part of Chapter 2 and selecting "Kay is right" option twice.

Wealth
Acquire over 20000 credits



You can re-explore locations, but i usually not had money issues, so the best location to grind up to 20k credits unlocks at Chapter 3. Just explore Lumen Cave 991: Sam for 20 lumen herbs, sell them at Black Market Bazaar: Silk Oasis and repeat.

Mail has been read
Read the message



Should unlock nearly at the end of the game. Just read all received mail.
Locations 1
There are 2 different type of location achievements, so i believe this could create some misunderstandings. The good news is: both could be finished in different playthroughs. I got both "all" achievements in my second playthrough midgame, while exploring the locations i missed during my first game.


Just Looking Around
Visit over 10 different locations



A Purposeful Visit
Visit over 30 different locaitons



The Ultimate Guidance
Visit all locations



These locations reffering to sublocations, like marked on pictures. For example a big starbase usually have 3-5, you need to click on all to make it count:
Locations 2
First Time To Thousand Peaks
Visit over 10 locations in Thousand Peaks



Traveler of Thousand Peaks
Visit over 50 locations in Thousand Peaks



Thousand Peaks is My Home
Visit all locations in Thousand Peaks



These locations are the locations you can see on the map. This include planets, the star of the system Ignis, the caves you can find by looking for Starsongs, military bases and the last one could be the reason why this achievement is quite rare. The most missed one might be the Military Station next to the Star Ignis, at the Chapter 2 area, as visiting it deadly if you dont have Forged Visa, but that could be acquired only during the Chapter 3.
Chapter 2
Doesn't need help
Protect as Jun



First achievement based on decisions, select the marked answer to get the achievement:

I'm not afraid
Not listening to Kay's advice



This is actually an unmissable achievement, because the other answer result in death:

Remember her generosity
Help to return a favor



Once escaped the pirates you will have another decision, select the following for the achievement:

Clan Edict: Leave None Behind
Choose to offer help to Bones



Select the following when you encounter Bones for the second time:

Not asking for return
Let Eda decide



Timestamp on video: 2:58:00
Sometime after the funeral, Eda ask Jun to join the crew. Jun will make this decision when first leaving from Recycling Station: Trash Mountain and you need to select:
Chapter 3
Not telling anyone
Decided not to send out the letter



Timestamp on video: 5:12:05
Jun writing a mail to the Clan Master while during a cutscene while travling to .... . This happend around the same time when you can control Remi the first time. You need to decide about the content of the mail, but that is irrevelant, just don't send the mail:

Die! Die! Die!
Shoot the dart 10 times



Timestamp on video: 6:10:30
While controlling Remi you need to craft the forged visa. This happens when traveling first to the location Mt. Aurora Cave: West Mount Tonitrus. During this scene there is the dart in the area, use it 10 times for the achievement.

Not suspecting anymore
Trust in Remi



Timestamp on video: 6:53:03
During the exploration of cave Ironwind 32 Remi will misscalculate the arrival of the authorities so there will be some unwanted visitors. After that select the following option to get the achievement:

Remi, prepare for landing!
Never been hit once by the space debris



The final goal of Chapter 3 to explore a cave, called Asteroid 99. To reach that cave you need to go through some debris without taking any damage. This is quite easy, but alt+f4 and reloading from last checkpoint might work here too if you take any damage.
Timestamp on video to check out what you can expect: 8:02:10 - 8:04:30

Forgive the past
Thank Remi



Timestamp on video: 8:38:00
Nearly at the end of the chapter, you need to thank Remi for saving you for the achievement:

Not lying
Be honest to Eda



Timestamp on video: 9:08:45
Very first moment of the Chapter that Jun receive a message from the Lee Clan. Tell the truth to Eda that it was from the Clan:
Chapter 4
Dodge that, Remi!
Not getting hit once when landing on Banshee



Timestamp on video: 9:15:20
Another reaction minigame. Avoid the comet parts of the Banshee comet while getting close to it. I found it more difficult, while i got it on first try alt+f4 should work if you fail it. If you see any message that 2X armor left then you need to restart from checkpoint.
Collect all memories achievements
The first 2 achievements for this category quite simple and nearly unmissable:

I Keep Remembering
Acquire over 20 items



Reliving the Past
Acquired over 100 items



Just couldn't let it go
Acquire all items



This last one is what is not easy, but at least you don't need to collect all of them in a single playthrough. For the full list of memories check next tabs.

So Long as You Follow the Lumen
See all 3 acts of "Melody of Starsong" with Eda, and return to Phoenix



See all 3 acts of Melody of Starsong IN THE SAME playthrough. Act 3 is the easiest to miss as you need to backtrack for it a lot, check memories for their locations, all 3 is in the "Myrian Mythology memory category.

Achievement unlocks later once you got all 3, for me, when i got the third, i just returned to the main menu and it unlocked at that time, if you just replaying the game and was a Phoenix already.

Memories: Pieces of my journey, Part 2
"47: Directions: Ship Traffic Intel -> Spaceway Beacon Intel While exploring for the first time here, you will get an event, select: “Try hacking into the beacon…” Memory received in case of a successful roll."

I guess you mean "Spaceway Beacon: Eiffel" instead of "Spaceway Beacon Intel"?

@InkyPaws because those achievements refers for differnt location types, as stated in my guide. You probably missed to visit a planet, the star or some military turret, which count for thousand peaks, but those dont have sublocations, so not counts for ultimate guidance

I've managed to get 'The Ultimate Guidance' but haven't got 'Thousand Peaks Is My Home' and I am baffled as to why.

"The most missed one might be the Military Station next to the Star Ignis, at the Chapter 2 area"
Where is this place? I tried to crosscheck with the neoseeker guide here so i dont miss anything but i cant find it. Is it ignis no. 1 and ignis no. 2?

Thanks a lot for your guide! I was just going to pull my hair out on the collection of memories until you updated th:heartp:e guide
Csontzuzo  [autor] 6 jun. 2022 às 1:56 
@Sivlero32: thanks, i was aware it was fixed some time ago, but i also missed 1 single memory and because originally i played at the release i not had any chapter checkpoint start, so needed to go through on the whole game again (for the third time, and a story game not that entertaining for the 3rd time, no matter how good is it), and i kept delaying this replay. But now i updated the guide with my notes about collectibles, extending with the last one i found, and the new achievements, so the guide now finally up to the version i planned:-)
