We're always working to give you a better experience and fix bugs.
Only the current version so far — new entries appear as the game ships updates.
It all starts with a message. Behind it: a 1954 nuclear test, a frequency we're all hearing without knowing it, and a silent colonization that has been advancing for decades with no one to stop it.
A CONSPIRACY THRILLER IN YOUR MESSENGER
Castle Bravo is an interactive story where characters text you, send you voice messages, photos, and files. The story combines declassified nuclear test records with interactive fiction.
YOU WRITE IN YOUR OWN WORDS
You write freely to the characters instead of choosing preset responses. They react to what you say, and each conversation builds a different relationship: who you trust, what you share, how far you go. An authentic, immersive experience where the way you talk is part of the game.
FEATURES
- Mystery and conspiracy game told through messages
- Open-ended responses: real conversations with the characters
- Voice messages, photos, files, and documents sent straight to your phone
- Based on real events
