On the surface, Five Nights at Freddy's 2 works very similar to the first game - you play a night security guard, watching cameras and switching on lights to ensure animatronic monsters don't make their way to you and kill you.
A couple key differences with the second game.
1) You have a flashlight, as well as the ability to shine a light while looking at security cameras
2) You have a Freddy Fazbear suit that you can put on quickly, often fooling the animatronics that get too close, and
3) There are now mini-games, which to be fair took a little work (and wikipedia help) to both figure out and understand how they connect to the backstory of the game.
The game also includes a music box which requires constant winding or a terrifying puppet creature comes after you with little chance to stop it.
At this point I realize that there are enough creatures in the game I should dedicate a post to them all...
