I soloed my way through Pirates Beyond Time made for ICONS. It is available for pay what you want/free at DriveThruRPG. I used The Four Color Hack to play it (3$) and the Mythic Game Master Emulator to solo it. The 3-4 hour adventure (twelve pages long) is for a Game Master and several player characters. I used three superhero characters to play through the five scenes. None of my characters died, though most of them got wounded. Make sure that your characters have a wide variety of powers and skills. This will help quite a bit. Save the world by taking out one supervillain at a time . . .
