A signal under the ice. A crew with too little time. A choice Earth will not understand.

Kryonull is a cinematic science-fiction visual novel set on Europa, the frozen moon of Jupiter. The expedition ship Sirena descends toward a thermal anomaly beneath the ice and a repeating radio pattern that sounds less like noise with every minute.

Every decision changes the mission profile: preserve the relay or chase the signal, drill slowly or force a narrow window, answer the ocean or leave in silence. Trust, hull integrity, oxygen, evidence, and biological risk shape the route to one of several endings.
