This walkthrough covers Part 1 of MIO: Memories in Orbit, focusing on the early game progression through The Severed Spine and the Dwellings zone. Players will unlock the map system, obtain their first major ability, collect modifiers, and defeat the first two bosses.
After the opening cutscene, move right through the short platforming sequence. Drop down to the lower platform to progress. At this point, only basic movement and double jump are available.
Continue right until a hook pulls the character upward, transitioning into the main game area.

First Area and Checkpoint
The character wakes up in a dark room on an operating table. The map is unavailable for now. Move left to begin exploring, then briefly head right to break a Junk Pile for Nacre.
Return left and follow the main path, defeating the first enemies along the way. Climb the pipes after the next encounter. From the second pipe, double jump left to reach a hidden platform and collect the Flash Memory note. Return to the main room and climb higher to find another Junk Pile guarded by a robot.
Head left through the door and cross the bridge. After a short cutscene, continue forward to reach the Nexus Attuner, which serves as a checkpoint and healing station.

The Severed Spine
Use the pipes near the Attuner to reach The Severed Spine. Move left to find a strange object that briefly speaks, then enter the building and call the elevator.
Before using it, go left through the grate to find a hidden area. Drop down and interact with the Strange Tube to meet Samsk, who asks the player to search for Tomo.
Use the elevator to reach L1: The Spine, then explore briefly before heading to L2: Apartments.

Apartments and Dwellings Entrance
In the Apartments, defeat the enemies on the lower floor, then use the chandelier to reach the upper platforms. Take out the remaining robot and continue upward.
Open the door leading outside to reach the frozen Dwellings zone.
Before progressing, return to the Apartments and intentionally die by falling into the red vines. This triggers a short scene and allows interaction with Shii back at The Severed Spine.
Speak with Shii and offer Nacre at the Pond. This sets up the map system, which will be unlocked shortly.

Dwellings
Enter the Dwellings and head left across the icy terrain. Speak with Rostam near the locked gate that leads to Metropolis.
Continue right, slide under the ice, drop down, and defeat the enemy below. Backtrack upward and cross to the upper right section. Slide across the ice and clear the next group of enemies.
Use the Nacre Basin if healing is needed, then continue forward. Slide down the icy slope to cross the red grass area automatically and proceed until reaching a hole in the ground.
Drop down and open the door to free Rad, who rewards the Analyser Modifier, allowing enemy and boss health bars to be visible.

Unlocking the Map
Use the shortcut to return to Shii. Offer enough Nacre and choose the option to look through his eye to unlock the map. Rest at the Attuner and equip the Analyser before returning to the Dwellings.
Continue left from Rad’s location, clearing enemies along the way. Trigger the gauntlet encounter and open the container afterward to obtain the Protective Overlay Modifier.
At the next door, take the hidden path first. Drop down into the pipe and enter the broken pipe on the left to find the Kinetic Thrust Modifier. Return to the main route once collected.

Boss Fight: Egis, Worn Out Sentinel
Progress through the area until reaching the large staircase. Break the crystal wall on the right to unlock a shortcut, then descend to the boss arena.
Egis uses slow, clearly telegraphed attacks. Dodge his dash, combo swings, and slam attacks by staying mobile and jumping frequently. During the second phase, his attacks chain together, but he becomes briefly stunned afterward. Use these openings to deal damage and finish the fight.

After defeating Egis, continue right and drop down to find another Strange Tube. Speak with Samsk to trigger a cutscene that unlocks the Hairpin ability.
Complete the short platforming section using Hairpin to return to the main world.
Boss Fight: Acat, Nacre Engraver
Use Hairpin to progress upward and unlock shortcuts back to The Severed Spine. Heal before approaching the next boss.
Acat primarily attacks in front. Use Hairpin to stay behind him and attack consistently. During the second phase, grapple points allow players to stay airborne and avoid shockwaves. Keep positioning behind Acat to finish the fight safely.
