Pasadena, 1938.
A heavy wooden crate appears at your door. No return address. No markings-only a sealed letter from a trusted friend in the military.
"You must not open it. Arm yourself. Lock every door. Whatever happens... don't let it out."
You didn't open it.
But whatever's inside doesn't need your permission.
What follows is a night of unraveling sanity and escalating terror, as a seemingly inert artifact-stolen from a secret Nazi research facility-becomes something far more dangerous.
Something alive. Something growing. Something feeding on everything... and everyone.
