"Five Nights at Freddy's 2 (FNaF 2) is a highly acclaimed survival horror game, serving as the thrilling sequel to the original "Five Nights at Freddy's," masterfully created by Scott Cawthon. It plunges players headfirst into the heart-pounding world of Freddy Fazbear's Pizza, an eerie animatronic-themed restaurant, where they once again step into the shoes of a night security guard. This time, they'll face a brand-new crew of animatronic characters and an ingeniously tweaked gameplay mechanic.

The controls for "Five Nights at Freddy's 2 (FNaF 2)" may differ based on the platform, but they generally revolve around mouse clicks or touchscreen interactions for operating cameras, flashlights, masks, and other in-game actions.

In Five Nights Harem II, players are tasked with spending a night shift in a fictional restaurant while avoiding being attacked by mechanical animals roaming the building. These mechanical animals include Freddy, Bonnie, Chika, and others from the first game. Also introduced is a whitened ghost named Freddie the Golden Bear and two new characters, a golem-like Maryette and a humanoid mechanical animal known as Balloon Boy.

Similar to the first game, players are confined to an office and cannot leave, but can monitor the movements of mechanical animals through a network of security cameras. The office has three entrances, a hallway, and two side vents through which mechanical animals can pass. Unlike the game in the previous installment, these entrances cannot be sealed but can be checked using lights.

Monitor the Cameras: Keep an eye on the various security cameras that track the movements of animatronics throughout the establishment.

Flashlights: Use your flashlight to illuminate dark areas and check for lurking animatronics. Be wary of its battery life.

Mask: When animatronics are around, you can put on a Freddy Fazbear mask and fool them into thinking you are one of them. However, not all animatronics are fooled by the mask, so use it strategically.

Ventilation: Watch out for the ventilation system, as some animatronics can crawl through it to get to your location.

Audio cues: Listen for audio cues that may signal the presence of animatronics, helping you anticipate their movements.

FNaF 2 takes the rock-solid foundation set by its predecessor and cranks up the intensity with a fresh set of challenges and exhilarating moments. It's a game that calls for quick wits, strategic thinking, and nerves of steel as players confront a whole new generation of animatronic frights in the spine-chilling domain of Freddy Fazbear's Pizza!"
