How To Guides
Quick answers to common "how do I…?" questions in MIO: Memories in Orbit. Each section links to the full guide for more detail.
How to reach Celestial Bay
Celestial Bay is an optional area at the very top of the map. From the room where you got Asma's Voice (above Nexus), climb above the left-side door, then glide to the platforms on the right. Follow the path to reach Celestial Bay. Unlocks the "Déjà Vu" trophy. You can find an Overseer (fast travel) and the Orphaned Shoe (one of 7 Curios) there.

The Crucible is the hardest optional platforming area and is required for the normal True Ending path. Completing both gauntlets unlocks Flowing Steps (walk/climb on gloom water), which leads to the Library and Boss Shii.
Access checklist
- Progress the story until you have the four Voices (Eye, Breath, Blood, Hand)—you can do this before or after the standard ending.
- Find the Severed Fingertip in the pit beneath the Vaults (where The Hand first grabbed you—drop in, head far east).
- Take it to The Wheel in the Lab (above The Hand fight). Repair the broken mechanical hand.
- Solve The Wheel puzzle (positions 0 → 120 → 240) to unlock the Vault Shuttle route and finally open the drop into The Crucible. Full sequence: Secrets — The Wheel.
- Inside The Crucible, finish two platforming gauntlets (typically one focusing on rising/falling hazards, one on rotating blades). Interact with the computers at the end of each, then talk to Tomo in the center to receive Flowing Steps.
Survival tips
- Enable Ground Healing in Assists so you can stand still after a near-miss and regain a shield layer instead of dying out of the segment. Details: Assists guide.
- Recommended modifiers from community guides: Gratitude (shield regen when staying grounded) and Maintenance Hack if you want to use Nacre Basins inside the area more efficiently.
- Swap to a mobility-focused build at a Network Gate before entering; this is not a DPS check.
- After Flowing Steps, go to the Canopy (via Bell Tower / Haven) and climb the gloom waterfall to reach the Library for the True Ending—see Endings.
How to reach The Pit
The Pit is at the very bottom of the map. First find all 6 Fragmented Serial Numbers to unlock the Manufactory. At the end of the Manufactory you'll find the door to The Pit—it only opens if you have the Defective Core modifier equipped. You get Defective Core by finding all 12 Candles and taking them to Asma above the Nexus.

Mel disappears from the Nexus later in the game. To save him, go to the Vaults: through the drawer in the large room, activate the pumps, and at the end jump down the pipe. Defeat Dr Halyn's Collector there—this rescues Mel and unlocks the "Rescued" trophy. After saving him, Mel will sell an additional item needed for the "Out Of Stock" trophy.

The game does not give you a map at the start. You unlock the map function later through story progression. Once unlocked, new routes you explore won't appear on the map until you return to a Network Gate (save point). This encourages careful exploration and memory.
