Five Nights at Freddy's 2 is a survival horror game developed by Scott Cawthon and a sequel to the original Five Nights at Freddy's game. It was released on November 10, 2014 for Android devices and has since become one of the most popular mobile games in the horror genre.

The game takes place in a pizza restaurant called Freddy Fazbear's Pizza, where the player is a security guard working the night shift. The player must survive five nights while being stalked by the animatronics, which have been updated from the previous game. The player has access to security cameras and doors to keep the animatronics out, but must conserve power to keep the doors and cameras active. The game has a variety of jumpscares and a tense atmosphere that keeps players on edge throughout the night.

Compared to the original game, Five Nights at Freddy's 2 adds more animatronics to the mix, each with their own unique characteristics and behaviors. The game also features a new "toy box" mode, which allows players to customize the difficulty of the game by adjusting the behavior of the animatronics.

While the game has been praised for its intense gameplay and jump scares, it has also been criticized for its repetitiveness and lack of story. Nevertheless, Five Nights at Freddy's 2 remains a popular choice for horror game enthusiasts and mobile gamers alike.
