No, did you look at the video? I know its fake, but roblox sounds?
I'm sure Roblox got their footstep sounds either from
a. a website (as I have found lots of "their" sounds in different websites)
b. or recorded them from real life
So who gives a stuff about which sounds they are from, as long as they give the general idea of footsteps.
Also if anyone wants to make this,
this place has some really good footstep sounds.
