Maximum Apocalypse: Gothic Horrors adds two new apocalyptic scenarios, Cthulhu and Vampires. Face off against life-draining vampires, ghouls, and werewolves in a classic monster set or try and stop a bunch of cultists from summoning Cthulhu or other unspeakable Lovecraftian horrors. Each apocalypse brings with it new gameplay mechanics such as the Insanity deck of phobias or the new night/day event deck. This expansion also adds two new survivor characters, the Priest and Ronin.
