It looked safe.

Comforting, even. An angel... what could possibly go wrong?

Together, you stepped through.

The door vanished behind you.

Then — silence.

The collars tightened.

Beeping sounds emerged, slow at first... then faster.

Then screaming.

Panic took over.

Some cried. Some prayed. Others turned on each other.

One by one, they fell.

BOOM.

Each beep brought another death.

Until it was your turn.
