Five Nights at Freddy's 2 (FNAF 2) continues the story of Freddy Fazbear's Pizzeria, a restaurant where terrifying animatronics are present. You will be the night security guard. And you need to stay alive until morning, when Freddy, Bonnie, Chica, and others may have tried to get into the security office.
Your main tool is the security camera system. By moving the mouse, you can switch between screens at different camera angles in the pizzeria.
In FNAF 2, a different mechanism will be introduced, when you wear this mask, the animatronics will be tricked into thinking that you are one of them. If you see a robot approaching your office, quickly put on the mask to avoid detection and survive another minute.
You have a flashlight in addition to the camera and mask. Use a flashlight to check the dark corners of the pizzeria, especially vents where the robot might try to sneak in. However, when using devices, be careful with power sources; they have limited power, and if they run out, you will be vulnerable to attack.
