Five Night At Smoke's had a interesting devellopement history i think you can already tell and only one single demo was released.

This demo including three full room but suffered from a lot of issue mostly ton of bug and people were confuse about mecanic due to the lack of phone call

So to fix those issue here Legacy Edition a updated demo included a lot of new stuff including but not limited too :

More night

A all out mode

New better looking ui

a lot of bug fix

tutorials

Please keep in mind that while the game will have enough night and extra content to be considered a " finish game " it will still not be

as much content as the original Five Night At Smoke's for that you better wait for dx you can expect legacy edition to be out quite soon
