Game description from the publisher:
Cthulhu!!!: Hastur La Vista, Baby! thrusts you into a desperate fight against elder forces from beyond space and time. You place the stalwart private detectives and quick-thinking girl Fridays who've stumbled onto the Cult's plans, and it's your job to find and sanctify enough ritual sites to prevent the avatar's arrival. For good or ill, you're already a bit unstable from years of mythos-busting and not above using the Cults' relics yourself. You can resist the objects' siren call long enough to save the world...can't you?
Designed for 2-6 players, Cthulhu!!!: Hastur La Vista, Baby! features an ever-changing map of downtown Kingsport, a 1920s Lovecraft Country city besieged by deranged cultists, frightening creatures from beyond the stars, and an endless supply of mythos mayhem. Players take turns placing map tiles, fighting Hastur's minions, collecting relics of power and striving to save the world from imminent destruction. Every game is different, and the strategy evolves with every new tile that hits the table.
