Cosmos has shown up near a strange gate, asking you to go inside and assist with some kind of test.

The worlds behind the gate intertwine in a tapestry of mystery—

"Kind Rover, may you find your fortune in the lucid world."

# Details

- Enter the simulated field and defend the experimental devices until all Tacet Discords are defeated. During combat, Cosmos will provide special Echoids to help the Resonators.

- Co-op will be available in certain difficulties, so you can team up with other Rovers to defend together.

- As the difficulty rises, you will face more waves of enemies, and will also unlock different Echoids.

- For each level, achieving the point requirement will earn you level rewards. You can re-challenge the same level to accumulate more points, and claim point rewards as you achieve total point requirements.

- If you have any unclaimed rewards when the event ends, you can log in within 30 days afterward to receive these rewards via mail.

You can only use designated Echoids in this mode (Sonatas will remain effective, but the main Echo Skill will be replaced).
