I hope I am not being toooo vague here , but then here goes
on the right side of the Fallon's Department Store (facing it) & across the street there is a garage kind of an entrance with a big arrow on it. once inside I met some cockroaches and then there's a puzzle ( i think) involving some numbers . as far as I can recall, there are numbers like 1,2 ,3,4 etc mentioned on the wall there.
if anyone's getting what I am saying here , can anyone tell what those numbers are for ( what secret does it unveil) ?
