User Summary Designed by Ed Anderson and illustrated by Matt Haley. ZDAY is a choose-your-own-style adventurer that starts you off at the beginning of a zombie apocalypse and forces you through a series of scenarios and choices to see how long you will live. The game is presented primarily in text and starkly illustrated comic-book-style images. There are multiple pathways through the game, depending on the choices you make. And of course there are hordes of bloodthirsty zombies.
