To collect RetroSpace's side-quest items, Mutamods, tech gadgets, audio logs, collectible cards, and star-head rooms, follow the location lists below. Several collectibles are missable because they are tied to a timeline, a quest choice, or the point of no return.
Side-quest items and objectives
- Mia's pink unicorn: Find the plushie in the alt-timeline Medical Section or in the current-timeline Luxury Section's Love Lounge, then give it to Mia.
- Nebula's diary: Take the diary from behind the painting in Marco's office and complete the related Nebula objective.
- The date: Speak to Mia and Joey before leaving for the alt timeline to hunt super-beings, then deliver their messages to each other.
- The secret weapon: Collect the three components below. The completed weapon appears on the workbench instead of being handed over by Marco.
- Charley: Do not escape from the Crew Section. Either kill Charley or place four heads in the ritual bowls.
- Joey's new head: In the alt-timeline Luxury Section's Private Rooms, find the Repli-baby wearing Joey's head. Take it back to Joey.
- Rose: Find a rose and a handwheel, then place them in or on the red container on the first floor to deal with Rose non-lethally.
- Violet: Find Violet in the pond in the alt-timeline Great Dome. Her note is on a second-floor counter in the alt-timeline Borealis Garden Laboratory.

Tech gadgets
The tech-gadget achievement requires buying every tech gadget at least once at level 1. The supplied location data does not provide an individual gadget list or shop-by-shop locations, so use the available vendors and purchase the complete gadget inventory. On higher difficulties, prices are higher and the achievement can become missable if credits are spent elsewhere.

Point-of-no-return reminder
If you are also working toward enemy-related collection objectives, after speaking to the Void Child in the Cockpit, do not return through the tear immediately. Explore the station first, because some alt-timeline enemy types must be encountered before that transition.
