Didn't get very far,
, some early impressions:
+Sound is really good. You feel like a big daddy, the random sounds of rapture are done well and add to the atmosphere
+New hacking is awesome. Makes sense, is quick, and the fact it's real time makes it pretty hectic at times
+Drill is cool
+Big Sisters are challenging. I managed to beat the first one without dying atleast
+/- Not sure about Multiplayer yet. I only played 2 matches, but one of them was 3 vs. 5 and it is a snowball effect of bullshit. They all stuck together and were nearly impossible to stop, once you died once they all researched you and made it even harder. Also seems like higher ranks get ridiculous advantages. Was also fairly choppy.
+/- Ammo is scarce, you burn through medkits and money now. Seems like a good thing for the most part, except....
-You're a big daddy. I love how they sound and the drill, but man gameplay wise they completely dropped the feeling. You are so damn weak, I think jack with a drill would tear it up more than you can. The game is way harder, but it feels like it shouldn't be and that you should take a much bigger beating.
-The vending machines not having sound. Actually added a lot more to the experience than I realized, and I already know it's being addressed in a patch...but I don't know how they missed it in the first place, and I'll have the game beat by the time it's fixed. Also odd how they work in MP.
-The graphics. Art design makes it look good, but this really looks just like bioshock 1. Spending time actually looking close at stuff shows some pretty ugly textures, the worst thing so far was probably the underwater part, the jellyfish are hilarious.
-As awesome as the sound is, the two guns I have so far sound pretty weak.
-Escorts. I see that getting old fast.
