From your small office you must watch the security cameras carefully. You have a very limited amount of electricity that you're allowed to use per night (corporate budget cuts, you know). That means when you run out of power for the night- no more security doors and no more lights! If something isn't right- namely if Freddybear or his friends aren't in their proper places, you must find them on the monitors and protect yourself if needed!
Can you survive five nights at Freddy's?
