Infamous Second Son is a 2014 action-adventure game developed by Sucker Punch Productions and published by Sony Computer Entertainment. The standalone sequel to 2011's Infamous 2 and the third installment in the Infamous series, the game was released for the PlayStation 4 on March 21, 2014. The player-controlled protagonist possesses superpower abilities that players use in combat and when traveling across the city. The story follows protagonist Delsin Rowe fighting the Department of Unified Protection (D.U.P.) in a fictionalized Seattle. Over the course of the game, Delsin acquires new powers and becomes either good or evil as player choices influence his morality. Sucker Punch began developing Infamous Second Son as early as 2011, when it began discussions with Sony on bringing the Infamous series to a new generation of hardware. The developer provided feedback to Sony on what hardware evolutions it would like to see on PlayStation 4. Sucker Punch considers Second Son a "fresh start" for the series because it features a new protagonist. Delsin's powers were designed to feel fluid and suited to the open world design. Infamous Second Son received positive reviews from critics, who praised its gameplay, combat, visuals and design, while criticism was aimed at the morality system, which some found to be dated and binary, as well as the repetitive side missions. The story was met with a mixed response, with some critics finding the narrative and characters to be a step backwards from previous installments in the series, while others viewed the writing as an improvement over its predecessors. The game sold over a million units within nine days of its release and six million units by June 2019, making it the fastest-selling entry of the Infamous series and one of the best-selling PlayStation 4 games.
