From publisher blurb:
The After is a setting of savage frontier action (think The Revenant or Jeremiah Johnson) in a sci-fi post-apocalypse (think Annihilation or The Quiet Place).
The After is set in the northwestern reaches of a broken North American continent. You play survivors of the shatterred human race trying to rebuild their world after decades of alien predation.
This Quick Start Guide has amazing art, a short introduction to the world of the After, four ready-to-play characters and a short adventure that will have your gaming group pursuing frontier justice against twisted mutant bandits in the Wind River Valley.
