Carnival of Madness

From the introduction: On the evening of Friday, October 30th, 1970, you’re driving down the Aylesbury Turnpike in western Massachusetts, headed for the Carnival Pandemonium. Most of the folks there tonight are families and couples just out for a bit of fun, games, and a little spooky excitement, but others have far more serious or even sinister purposes. Whatever your reason for being there, one thing is certain. Everyone at the carnival this evening will experience things unimagined in their darkest nightmares. You don’t know it yet, but the part you play may determine the fate of all humanity.
