So I might as well say what will change in the acts note: most of the acts will stay the same with miner changes

fnas 1: act 1 It will mostly be the same as the original but the power drains slower and tails will be able to go down both hallways and sonic will be able to go down both hallways there will be custom night challenges and there will be a survival night

fnas 2: act 2 will stay the same as the original but you’ll be able to charge you flashlight kinda like in fun times at homer’s 2 and the map/place will have a different layout and there will be two new characters named tails doll and confetti toadette and both withered yoshi and taingle will have redesigns and there will be a survival night and withered mario will have a new design giving him a cape and bowtie

fnas 3: act 3 will stay the same as the original but I’ll be able to see withered toy yoshi in the window when she’s coming and the map/place will have a different layout and there will be custom night challenges and phantom mario will get a redesign and there will be three new characters named withered taingle withered balloon toad and withered luiginette

fnas 4: same as the original but the fnas 4 dlc will be added basically be the hard mode of fnas 4 kinda like fnas 5 and plushnic and plushtails will be in as a fun with plushtrap thing after each night and in the dlc plushrio and plushi will be the same and the dlc will take place in the 2nd sonic’s hero pizza palace (but abandoned like in the normal mode) there will be three new characters in the dlc named toy bronze yoshi cobalt taingle and the clonemare there will be a mechanic where if you hear nightmare Mario or nightmare yoshi breathing at the door you’ll actually have to close the doors however the doors won’t work on nightmare sonic and nightmare golden sonic and there will be a survival night for both the dlc and the normal mode and nightmare mario will have a new design giving him a cape and bowtie

fnas 5 the first chapter: same as the original but in the hard mode will be mirrored to make it harder and origin sonic will get a redesign and the nights will be shorter (since in the original fnas 5 the nights were 10 minutes long)
