About

Echo

Features
Read full description

ECHO is an interactive sci-fi story told through a live communication link with Lyra Voss, an astronaut stranded on Mars. You do not pick from canned dialogue. You type what you want to say, and Lyra answers in character as the mission unfolds. The relay is unstable, messages can slow down or fail, and the story is built around the feeling that one fragile channel is still open between Earth and Mars. What you can do: - Start with Lyra's distress signal. - Reply freely instead of choosing preset lines. - Receive ongoing mission updates as the channel comes back online. - Use voice input to dictate messages before sending. - Stabilize the relay with optional short-duration access passes. ECHO is a fictional narrative experience. In-app purchases expand short-term relay access; they do not unlock a guaranteed story outcome or force you to pay to rescue a character.
