Jack Atlas, self-proclaimed 'World's Best Assassin', had a simple plan: retire in style and marry the girl of his dreams. Instead, he gets magically transported to The Tower—a divine deathtrap where gods pit their creations against each other for the ultimate prize: eternal paradise for you and your friends. 

The catch? If you lose, well, let's just say your chances of finding a decent bar in oblivion are slim. 

Jack, a man who’s never met a hornet’s nest he didn’t want to kick, soon finds himself on the wrong side of The Black Centipede, a notorious assassin cult with a charming recruitment policy: join or they’ll murder everyone he knows and loves. Instead of sipping Mai Tai’s on some beach, he can’t pronounce, he’s now slurping down health potions after getting stabbed in his no-no square by an overzealous goblin. Now, his only goal is to  conquer The Tower, appease his assassin overlords, reunite with his dream girl, and avoid getting sent to 'dungeon timeout' for bad behavior.

 If anyone’s crazy enough to not just survive, but thrive against The Tower, it’s Jack.
