Well, infamous fanfiction is basically fan - made stories that are known for being bad in some way. It could be that they break the unwritten rules of the fandom. Maybe they rewrite the characters in a completely wrong way, like making a heroic character into a villain for no good reason. It can also be due to the author's behavior. For instance, if an author is known for plagiarizing other fanfictions or being rude to readers, their works can become infamous.
The story of Infamous 2 follows Cole MacGrath. He has powers and is on a journey to become more powerful to face new threats. He travels to a new city, New Marais, which is filled with all sorts of challenges. There are different factions in the city, some support him and some are against him. Cole has to make choices throughout the game that affect his powers and how the story unfolds.
