CHECKPOINT SAVING. Placed by the player with a sapling item which are admittedly unlimited. But still. Checkpoint saving in an immersive sim.
.. At least that’s how it first appears, but if one looks closely at the save screen it states clearly “Save points only save progress made since leaving the opening portal level”. I really, REALLY hoped that this didn’t mean what I thought it meant but… it does. Progress lost on quitting. On reloading the save, it places you at the beginning of the level.

Oh well. I'm out.

I'm playing wait and see. I played through both Underworlds in the last couple of years, so the originals are fresh in my mind still. After reading reviews on Steam, it seems very unfinished. I expect similar mixed reviews and disappointment when System Shock Remastered eventually comes out. Hopefully GOG eventually stocks it.
