RetroSpace has many achievements you can unlock, including difficulty runs, challenge runs, story endings, collectibles, side quests, and enemy-related tasks. Some achievements are easy to miss, especially the ones linked to the alternate timeline, NPC quests, Mutamods, weapons, and different station areas.
This RetroSpace achievements and collectibles guide will help you complete each achievement’s requirements and point you to the locations you need. You will also find the collectible card locations, Mutamods, station areas, NPC side quests, enemy types, and other achievement requirements here.
RetroSpace Difficulty Achievements
Out of madness
Requirement: Finish the game on any difficulty.
Complete RetroSpace on Story, Normal, 1999, or Russ Kurtell difficulty. If you finish the game on a higher difficulty, then you can also unlock the achievements for the lower difficulties.
Gotcha, Boomer!
Requirement: Finish the game on 1999 mode.
Complete the game while playing on 1999 difficulty.
I’m MacReady!
Requirement: Finish the game on Russ Kurtell difficulty.
This is the highest difficulty achievement listed here, so you will need to complete the game while playing on Russ Kurtell mode.
RetroSpace Challenge Run Achievements
Some of the hardest RetroSpace achievements require you to complete an entire playthrough with a specific restriction.
For these runs, you can reload quick saves and auto saves when needed. Avoid manually backing up and overwriting save files, as this can cause quest or achievement problems.
Hobo for life
Requirement: Finish the game without spending money in vending machines.
Do not buy any food or drinks from vending machines during the playthrough.
You can still spend money on Mutamods, gadgets, and weapon upgrades. The restriction only applies to spending money on food and drinks.
Never there
Requirement: Finish the game without being detected by any enemy.
You must complete the game in ghost mode.
Check your statistics during the run. Enemies Alerted must remain at 0. Avoid actions that alert enemies, even if you do not get into combat.
Warren Wrenchman
Requirement: Finish the game using only the Power Wrench and HyperBroom to directly kill enemies.
Do not kill enemies directly with other weapons.
Environmental kills, enemy infighting, and kills made by friendly security do not count against this achievement.
This is NOT the way
Requirement: Finish the game without ever using a helmet.
The helmet provides the HUD, including the minimap, health bar, visibility/noise information, ammo count, and quest information.
It also provides oxygen tanks. Without the helmet, entering a gassed vent will start damaging your health.
For this achievement, never pick up the helmet during the entire playthrough.
Clean hands
Requirement: Finish the game without killing anyone, including robots and turrets.
Keep your Player Kills statistic at 0 throughout the run.
Environmental kills, enemy infighting, and kills made by friendly security do not count.
I prefer my payment in cash
Requirement: Collect 2,000 credits without dying.
You need to collect 2,000 credits during a run before dying for the first time.
There are roughly 6,000–7,000 credits available across the station and both timelines, so you need to collect a significant portion of the available money without dying.
Are you okay, buddy?
Requirement: Play for at least 1 hour while below 20% health.
Keep your health under 20% for a total of one hour.
This can be risky during normal gameplay. You can stay somewhere safe and wait, or reload saves if necessary.
RetroSpace Ending Achievements
RetroSpace also has achievements for the two main endings.
Too good to be true
Requirement: Reach the Good ending.
Choose The Golden Journey as your destination.

Not the best outcome…
Requirement: Reach the Bad ending.
Choose Earth as your destination.
Check the endings guide above if you want to see the different ending paths and post-ending scenes.
RetroSpace Collectibles Achievements
For many achievements, you need to collect or purchase specific items. Some of these are missable because certain items are tied to specific locations or timelines.
Muta-Freak
Requirement: Buy all Mutamods at least at Level 1.
There are 10 Mutamods to collect. Some are exclusive to a location or timeline, so do not leave them until the end of the game.

Tech-guru
Requirement: Buy all tech gadgets at least at Level 1.
This achievement can become missable on higher difficulties because upgrades and purchases cost more.

Her note is in the alt timeline Borealis Garden – Laboratory, on a counter on the second floor.
The achievements also include Who is Dr. Nebula? and Who am I?, but these are part of the main story rather than optional side quests.
