I had the same question when I discovered these sort of games! Yep, 100% solo game. Play by yourself with a 6-sided dice, a deck of cards, jenga style tower (if you have one, not 100% necessary), and some to record your journey (a microphone, camera, pen and paper, anything you can write on).
ahhhhhh, thanks! that's awesome. i been slowly going through the bundle and was really interested in the combo of apocalypse and solo play. i didn't know these kind of things even existed for solo. now i'm gonna have to search more out.
