Posts at TTLG indicate that the game is just a straight up shooter. A good, relatively open shooter but still just a standard shooter. I think a Swedish journalist also said as much some time ago in a preview. Considering Ken Levine repeatedly said it was possible to play the game stealthily, I'm not too happy. You can't even walk in the game, and the splicers, supposedly don't react to any sounds you make.
There's been complaining all over the official forums. It's seems to me, like it's just the case of a very vocal minority making things seem worse than it is, though.
If you'd like to hear it I can sing it for you. It's called "Daisy."
Daisy, Daisy, give me your answer do.
I'm half crazy all for the love of you.
It won't be a stylish marriage,
I can't afford a carriage.
But you'll look sweet
upon the seat
of a bicycle built for two.
I'm afraid. I'm afraid, Dave. Dave, my mind is going. I can feel it. I can feel it. My mind is going. There is no question about it. I can feel it. I can feel it. I can feel it. I'm a... fraid.
That's the date for the release of Bioshock in Portugal, Spain, and I think France, as well. I wouldn't be surprised if the 31st was the release date in all of Europe except the UK.
Edit: The release date in France is, indeed, the 31st.
Tried the demo. Seems to run fine on my system with everything maxed out at 1280x960. Fraps indicates between 20 and 30 fps, though.
The graphics are sweet and the ambiance seems to be genuinely scary. The gameplay seems to be mostly run&guntm with added plasmids. I guess it could be described as a more actiony System Shock 2. The faster pace kind of clashes with the scary atmosphere, though. Here's hoping the full game plays differently...
