fnaf 2 lets the tension grow minute by minute, rather than plunging you headfirst into the action. You soon learn that working the night shift at Freddy Fazbear's Pizza is everything from peaceful. The player's mind is kept on high alert by the lengthy quiet, which doesn't reassure them but rather makes them feel uneasy, like the calm before a storm.
Fear is induced in fnaf 2 by the player's perception of being watched. Something is always closing in, even while you're sitting still in the confined workplace. The security cameras serve as your only point of contact with the outside world, but keeping a close check on everything at once becomes overwhelming. The game deftly forces you to make a choice: concentrate on one danger while disregarding others.
