Infamous is an action-adventure video game developed by Sucker Punch Productions and published by Sony Computer Entertainment for PlayStation 3. The game was released in May 2009. In Infamous, the player controls the protagonist Cole MacGrath, a bike messenger caught in the center of an explosion that devastates several city blocks of the fictional Empire City. The explosion sends the city into chaos while Cole finds himself with new electricity-based super powers. Though the game's story follows Cole using his new abilities to restore some semblance of order to Empire City, the player is given several opportunities to use these powers for good or evil purposes in the game's Karma system. These choices ultimately affect character growth, the reaction of the city's populace towards Cole, and finer elements of gameplay and the story.
