FNAF 2 stands out for its gameplay, which requires players to memorize the patterns of each animatronic in order to devise appropriate strategies for each night. Each figure approaches the office in a unique fashion, from strolling through halls and appearing in ventilation systems to abruptly standing directly in front of the player. This requires you to constantly switch between surveillance cameras, flashlights, and the Freddy mask in order to react appropriately to each situation.
