Ever since I purchased my Playstation 4 I have been waiting for a good next-gen game that was developed specifically for this system. inFamous: Second Son is that game and more. The visuals are stunning and the gameplay is solid, though a bit repetitious at times. In the game you can choose to be a hero or a villain. I started off my first run through on the hero side of things on the normal difficulty setting. It was a blast! Some of the boss battles were a bit frustrating, but not overly so (boss battle video: https://www.facebook.com/photo.php?v=10152331049620692). I was able to complete the game at 100% and it was interesting leveraging the different powers to defeat different enemies. Now I am working on the villain side of things as there are different powers available.
In one of the recent updates to the game Sucker Punch added a feature called photo mode. This feature, once enabled, allows you to pause the game at any point, manipulate the camera in a variety of ways and take a picture. These pictures can be shared on Facebook and Twitter. You can see a sample from my "villain" game below.
You can manipulate the camera quite a bit in this mode, even the f-stop! One gamer site, NeoGAF, is running a photo contest for photos from the game and some of them are pretty spectacular: http://www.neogaf.com/forum/showthread.php?t=805887
So, if you have a Playstation 4 and are looking for a great game with some interesting extras you should check out inFamous: Second Son.
