During the Credits
There is a trophy unlocked, clips of characters, and other various scenes from throughout the game shown alongside the credits as they roll.
After the Credits
There are various extras featured after the credits of Infamous: Second Son.
Right after the credits are finished there is a message congratulating the player. The message suggests starting over and choosing a good or evil path (depending on the way the player completed the first playthrough), but recommends firsts going through the rest of all the side-missions that might have been missed and collecting every single Blast Shard and driving the D.U.P. out of Seattle.
