Matrix is the first Archive in Child of Eden. It is themed around digital technology and the color orange. It is split into three sections.
The archive begins as a thousand square tiles form an image of Lumi, in distress. The player then navigates through a tunnel of cubes reflecting imagery, purifying viruses along the way. The player reaches the end of the portal, revealing the Cubed Core.
- Digital Jellyfish
- Red Cube
- Tentacle Core (Mini-boss)
- Cubed Core (Boss)
The archive's music is based off of the Genki Rockets song Fly! from the album Genki Rockets I: Heavenly Star. While the base song does not use musical cues from Fly! (aside from the end), sampled sound effects feature vocals from the song.
