Cliffhanger: Challenger of Tomorrow is a 300,000-word interactive novel by William Brown, author of The Mysteries of Baroque. It's entirely text-based, without graphics or sound effects, and fueled by the vast, unstoppable power of your imagination.

Here, masked and caped adventurers with ray guns and rocket boots blast down the gleaming Art Deco streets of Manhattan. Sinister criminal masterminds scheme from tropical island lairs. Dinosaurs stamp and bellow in fog-shrouded jungle plateaus. Fearless archaeologists discover incredible secrets and terrible curses under the desert sands. Master thieves plot daring heists among the glittering casinos of Monaco.

And you? You're Challenger, the most famous adventurer in the world—or, if you like, the most infamous scoundrel. You were raised as an orphan by Dr. Cosmos Zeta at his Tomorrow Institute, where he and his crack team of scientists have developed "zeta rays," providing free energy for the whole world, and granting mysterious powers to a lucky few.

But now, Dr. Zeta has been assassinated before your very eyes, and replaced by a doppelganger, who accuses you of attempted murder. To clear your name and avenge Zeta's death, you'll have to chase the assassin around the world—and beyond!

Will you defend Earth against a sinister mastermind? Will you crush the axis of Fascism that rages across Europe? Will you uncover the shocking truth about the zeta rays?
