granite night
At underwater RE's specifically the 2 sea lab encounters in Taiga
the large one and the small one there is an encrypted disc on chemistry station in the large RE
and an electrical station iirc at the smaller RE the one with the 2 sets of neoprene suits
they are inaccessible you can see the interact button for a fraction of a second before it switched to the station no matter the angle you look at it. This is on steam on pc
