First of all I would clarify that the game will be available on several languages (voices, subtitles, everything!). Depending on your country language you can request right here on this post so I can add it to a better gameplay.

You will be able to play tapes that makes part of the game's saga lore and the tapes that are not part of. This is to be a better and expanded introduction to VHS-FNAF-styled games, or also you consider it as a fun addon. They will be also fully translated.

A sequel to the game is already on plans! It takes place on Security Breach and FNAF 6 (FFPS) timeline. More information soon.
