What about the tears and the skyline? And there's the traps you can lay as well.
Dumbed down in the sense that it's just a straight up FPS now. Bioshock gave you multiple ways to tackle a situation, you could hack the cameras and turrets, you could shoot them and get their items, you could run in all guns blazing or you could use stealth and the wrench, etc. Of course, this was also "dumbed down" from System Shock so the series was heading this way.
Have they said why they limited your ability to carry weapons? For me, that was the only area I felt was better in the original game.
