The story follows protagonist Cole MacGrath on his quest in New Marais to grow powerful enough to be able to face his nemesis, the Beast.

The game's music was composed by James Dooley, Bryan Mantia, the band Galactic, and Jonathan Mayer.

[1] Experience points are awarded for actions including defeating enemies, healing citizens and completing missions.

Certain actions, such as stopping to help injured citizens or killing them to restore Cole's health, will affect the Karma level in either direction.

[1] A feature called User Generated Content, or UGC, allows players to make their own missions and share them through PlayStation Network for others to play.

[1] Scattered around the city are hundreds of "Blast Shards" which Cole can collect to increase the amount of electricity he can store.

A month following the events of Infamous, Cole (Eric Ladin) and his friend Zeke (Caleb Moody) meet with NSA agent Lucy Kuo (Dawn Olivieri), who informs them that Dr. Sebastian Wolfe (Michael Ensign), the man responsible for creating the Ray Sphere that gave Cole his powers, has developed an even stronger version that would give him enough strength to stop the Beast.

Arriving in New Marais, Cole and his allies learn that energy magnate Joseph Bertrand III (Graham McTavish), an anti-Conduit demagogue, has seized control of the city.

Rescuing Wolfe, Cole learns that he has developed the Ray Field Inhibitor, a device capable of stripping Conduits of their powers.

While working to free her, Cole and Zeke meet Roscoe Laroche, a Vietnam veteran who leads a resistance movement opposed to Bertrand, and Nix (Nika Futterman), a Conduit with the ability to manipulate and ignite a black, napalm-like substance, who has been waging war on the Militia.

Using intelligence gathered by Zeke, Cole, and Nix, locate a secret lab where Kuo, revealed to be a Conduit, has been forced to transfer her ice-generating powers to an army of human mercenaries controlled by Bertrand.

With the Conduits and the resistance movement joining forces, Bertrand is killed in his mutated form, ending his authoritarian rule.

With the Beast in New Marais, Cole reunites with John White (Phil LaMarr), who he thought had died in the process of destroying the first Ray Sphere.

John admits that he has become the Beast and gives Cole a vision of humanity perishing from a plague born of the radiation from the Empire City Incident.

Nix eventually sacrifices herself as well, injuring the Beast and leaving Cole with just enough time to finish the process and supercharge his powers.

As Zeke takes his coffin out to sea for burial, a lightning bolt in the form of a question mark strikes in the distance.

In the evil ending, Cole sides with White, causing Nix and Zeke to turn against him and steal the RFI.

"[31] In October 2011, it was announced that PlayStation Move support would cover the whole game as part of an update which would come out sometime after Infamous: Festival of Blood was released, along with a new cutscene creation tool for the UGC creator.

Sterling McGarvey from GameSpy thought the story was a "pulpy comic book narrative",[51] Colin Moriarty of IGN found the story well-delivered and "incredible",[1] and Eurogamer's Christian Donlan found the endings of the game to be "genuinely satisfying" and an improvement on the overarching storyline of the series.

[3] IGN's Moriarty thought that New Marais was more living and breathing than Empire City and the overall look of the game was improved over the original.
