- the differents sound in the prison near the Toluka lake in Silent hill 2 (PS2)

DUDE! Remember there was something on a cell making noises, but it was invisible? That gave me the creeps back then because I didn't knew where it was coming from.

yeahhhhhh

SPOILER

but there was also a sort of "huge spider walking" noise in the big room at the end of the prison, I looked everywhere to find it
