FNAF 8 at a glance

Cast: eleven animatronics, more than the early games
Defence: a Freddy mask rather than a door you can hold
Office: redesigned, with a different set of entry points
Goal: five nights without losing your nerve
Cost: free in the browser

FNAF 8 is another part of the popular game, with new characters. As in the first part, the new guard will spend five nights in a frightening place with sinister dolls. During the day these dolls are quiet and peaceful, but at night the fun begins. In this game there are new locations and eleven monsters, as well as a new way to defend yourself. Try to stay up until morning and not go crazy with fear. In FNAF 8 the design of the office is changed, and so are the actions of the night guard. Wear the Freddy mask to fool the animatronics so they leave you alone.

Mask rules, if you have not used one before

Put it on when something is already in the room, not before
Take it off the moment the room is clear, because you cannot see properly through it
It does not work on everyone - there is always at least one that ignores it
Holding it on for too long is its own way of losing the night

The mask mechanic comes straight from FNAF 2, which is where it was introduced, and the two-door version it replaced is still on the FNAF 1 page.
