This is a true story

Aliens are real. They've been among us since 1954, and now they know you know.

It all starts with a message. Behind it lies a 1954 nuclear test, a frequency we all hear without knowing it, and a silent colonization that has advanced for decades without anyone stopping it.

A conspiracy thriller in your messenger

Castle Bravo is an interactive story where characters message you and send you audio, photos, and files. The story combines declassified records of nuclear tests with interactive fiction.

Write in your own words

Write freely to the characters instead of choosing predefined replies. They react to what you say, and every conversation builds a different relationship: who you trust, what you share, and how far you go. An authentic, immersive experience where the way you speak is part of the game.
