It's been a while since I played Bioshock but I could still recognize some of the iconic locations. Seeing Bioshock's scripted sequences reinterpreted for Doom was fun. The enemy layout feels mostly like an afterthought, though.
This WAD hasn't really aged well. The gameplay isn't particularly interesting and the levels rely too much on over-using ZDoom features. The new sound effects are annoying, and the announcer's endless chatter on map04 gets downright infuriating. The ending levels are disappointing, especially the final battle which can be over in seconds. That said, the detailing looks nice in some levels.
The atmosphere was gripping and the level design good, for the most part. It was exciting to grapple with some new enemies and the double-chainsaw was a heap of fun. There was never a moment I wasn't really feeling it, either because I was low on ammo and I could hear a few dozen terrible things shuffling around for me or because I had picked up some goodies and it was time to, in turn, visit terrible things upon the enemy.
The only reason why my rating isn't 5/5 is related to that "low on ammo" remark listed above. I found myself myself at the final battle without either the health or ammo to feasibly beat the level and had to backtrack in my progress through the WAD to ensure otherwise. This wouldn't otherwise be a big problem except for the fact that I found the penultimate level to be something of a bullet-sink, not to mention a health-sink too, depending on how much ammo you had going into it in the first place.
This broke the flow of the WAD for me, but it's otherwise rather polished and I highly recommend it. I'm hungry to rip into the sequel.
a fairly modern techbase level. nothing really to it, the combat is a little less fun than I originally expected, but it progresses alright. it's got an interesting name but on the overall onset doesn't offer all that much in comparison. relaxing.
