Ok, so technically it is, but this is the European release titled Exhumed. Nothing wrong with that, but the store page should at the very least reflect it. Beyond that, it's a good game. You may have to screw with dosbox yourself to get good performance out of it.
This port works well on windows 10 with no problems. There is nothing missing from the ps1 version that hurts the game in any way. (Psycho Mantis notwithstanding) There is even a first person view......for what that's worth. I say hook up a controller, set the controls as they were on ps1, and play away like nothing's different, because it's not different enough to hurt the game in any way.
