It is a map made by JP LeBreton, mimicking his levels from Bioshock. Unfortunately, it's been 10 or so years since I last played Bioshock, so I couldn't exactly compare the two.
The teleporting enemy at the start was a really nice touch. The level, in general, had a really nice atmosphere. The skybox and, if I'm not mistaken, tint-shifting do a good job of setting the scene.
Unfortunately, and this may have been the GZDoom settings I have, but the map wasn't all too helpful, and the level was rather complex, so it took me some work to get where I intended to go.
Regardless, I never had any real difficulty figuring out where to go, and the level seemed to flow pretty well. I do wish I had chosen a harder difficulty, but I had been burned by some hard Doom levels recently.
The Romero cameo at the end was fun too.
