You're probably already very familiar with the plot behind FNAF: it's a survival horror video game in which you've been hired as the night watchman of a pizzeria that is dwelled by animatronics.
That's the case of Five Nights at Freddy's that was released back in 2014, reaching a huge recognition among gamers from all over the world that have downloaded it massively despite not being free.

The proliferation of smartphones, whether Android or iPhone, has encouraged independent studios to develop loads of apps and games.
