Five Nights at Freddy's is a hugely influential horror game released by solo developer Scott Cawthon in 2014.
The game sees players take control of a security guard at a pizzeria. Said guard must survive five nights of being hunted by increasingly relentless animatronics.
Players can use a network of cameras to see where animatronics are at any given time, and can use resources to close doors in order to protect themselves against attacks.
