In solo play, you will play against a villain who has a lower starting hit point amount than in a game with multiple players. You will choose one of the four scenarios that come with the game. There are solo instructions for each scenario. These include an amount of turns that the scenario will last and a goal amount of fame the player needs to gain to become a Champion of Zeta City.
You will have to plan out your turns to make sure you gain enough fame to win. Interestingly, you might not want to just knock out the villain quickly since that might leave you lacking in fame. You have to give the citizens and reporters of Zeta City enough time to get to the scene and take note of what you are doing, so don't be in too much of a rush. Use your time wisely and try to gain as much fame as possible.
