Marvel's The Punisher combined a 173-year-old communication system with modern social media to reveal the titles of its 13-episode first season.

This afternoon the official Twitter account of the upcoming Netflix drama delivered one title in international Morse code every five minutes, leaving it up to fans to translate. Presuming these titles were tweeted out in order, here's the chronological list of episodes arriving on the streaming service later this year:

  • 3 am
  • Two Dead Men
  • Kandahar
  • Resupply
  • Gunner
  • The Judas Goat
  • Crosshairs
  • Cold Steel
  • Front Toward Enemy
  • Virtue of the Vicious
  • Danger Close
  • Home
  • Memento Mori

The titles don't give away much, but some perfectly suit the militaristic aspect of Frank Castle; titles such as "Resupply," "Gunner" and "Crosshairs" all fit within the theme, while "Kandahar" is in Afghanistan, one of the locations where Castle was based during his career in the U.S. Marines.
