Infamous: Second Son Won't Feature Multiplayer

Designed with single-player in mind.

Infamous: Second Son will not feature a multiplayer mode, according to the game's brand development director.
Ken Schramm clarified the situation in conversation with Taiwanese site UDN (via Dualshockers), where he explained that while Delsin will meet multiple NPCs throughout the course of the game, it's designed as a single-player experience.

Elsewhere in the interview, it was revealed the game has an open architecture, so you can do quests outside of the main story at your leisure. The one caveat with this is that certain situations only appear if you're aligned a certain way, so if you make certain choices you'll lose access to other situations forever.
When Infamous hits stores, two Collector's Editions will be available, as will a new PS4 bundle.
