All Collectibles in Sector 1: In Solar Power Plant

Generator Entrance - Storage Expander: In the first area, before a large locked door requiring two hacks, you'll find a doorway with a barrier. Return after obtaining the Lim Eraser in Sector 2. Destroy the lunafilament mass behind the barrier to get the Storage Expander, which increases Diana’s hacking gauge.

Power Distribution Center - Safe Box 1: Facing the large door with five locks, drop to the left and take the elevator. Jump across gaps to reach a lock. Near this lock, look down to find an area below. Jump down to this lower area where you can move platforms via a hackable node. In the back corner, find Safe Box 1 containing Lim.

Power Distribution Center - Safe Box 2: Before the moving lasers leading to the five-lock door, you'll see a laser barrier. Go past the moving lasers to the door, then turn around and look up to hack a node that disables the lasers. Head back to the initial laser barrier and drop down. Defeat the two Watches and a Crusher. Go up the stairs, avoid the lasers, and find Safe Box 2 at the end of the hallway.

Power Distribution Center - Safe Box 3: In the same area as Safe Box 1, stop at the lock you need to hack. Head to the opposite corner and drop down to find the Stasis Net weapon. Continue down the hallway past a barrier (the first Mini Cabin is on some containers here). Once you have the Lim Eraser, break this barrier and go through the door. Drop into the new room, defeat all enemies, and unlock the two chests to find Safe Box 3.

Power Distribution Center - Pure Lunum: In the same area as Safe Box 3, there is another Lim Eraser barrier near where you first picked up the Stasis Net weapon. Breaking this barrier will allow access to Pure Lunum.

The Concourse - Read Earth Memory 1 (Globe REM): This REM is obtained automatically as part of the story.

The Concourse - Mod (a community-made modification that changes the game) - Hardened Suit: After the room with the Globe REM, enter the next room containing the Main Control Lobby Station escape hatch. Next to it is a blue chest containing the Mod - Hardened Suit.

The Concourse - Cartridge Holder: In the same area as the Mod, enter the medical bay. The Cartridge Holder is directly in front of you and increases the number of heals you have.

The Concourse - Read Earth Memory 2 (Crayons REM): Beyond the escape hatch, head down the long hallway towards the elevator. Before the elevator, use the zipline to go to the top. On one side, interact with a wall to reveal a Holo-Wall. Dispelling the hologram reveals a room containing the Crayons REM.
