Trophies for the original Siren have leaked onto the net. Back in December, Siren was rated by the ESRB for the PS4. This is unrelated to the recent rating of Blood Curse, as this is a rating for the original Siren which launched back on the PS2 and was designed by the same producer/designer as the original 1999 Silent Hill.
There are 12 trophies to be earned. So sadly, no platinum. Siren was one of the best PS2 horror games and very easily one of the most difficult to finish. Sony has not officially announced the port, but the trophies have appeared on Sony servers which were then published by Trophy sites. Original source is below.
