During the Credits
There are scenes from the game shown alongside the beginning of the credits. The extra scenes then fade to black with the rest of the credits being normal black and white scrolling credits with no other extras.
After the Credits
There is a message saying that the clock has been wound back to before you take the last mission. Players can then continue to play in the open world and take on new missions they might have missed. But there are no extra scenes after the credits of Infamous 2.
