Five Nights at Freddy's: Security Breach is a survival horror with stealth elements. In the game, the player takes control of a young boy named Gregory, who is locked inside "Freddy Fazbear's Mega Pizzaplex", a large shopping mall that the player is free to explore. While locked inside, the player must survive from midnight to 6:00 a.m. while fending off several animatronic mascots and robots that attempt to kill them.[1][2][3] The mall and animatronics are modeled after a 1980s glam rock style.[4] Gregory will also encounter other types of enemies, such as the night guard Vanessa.[4]
Unlike previous iterations where Freddy is a prominent antagonist, in Security Breach, Freddy helps the player evade the other animatronics and features a stomach compartment that the player is able to hide in. However, as a result of malfunctions, Freddy can run out of power and must be recharged, forcing the players to fend for themselves.[1][4] A variety of different tools are available to the player besides Freddy, such as a network of security cameras accessible via the players' watch, weapons such as the "Fazblaster"—a laser gun with unlimited ammo—and the "Faz Cam"—a camera-like stun device— as well as environmentally based ways to deterring the animatronics, such as knocking over objects to create noise that lures away animatronics.[1] When the time reaches 6:00 a.m., the player is able to leave the Pizzaplex and complete the game, with the ending the player receives being dependent on how much of the Pizzaplex they explored.[1][2]
