I absolutely hate the UI in this game. I hate hitting up the number keys or the F# keys to get the combo that I want. Wouldn't a wheel be better served for this purpose? This really bothers me when I'm always slow to react to switch to the plasmids that I want. For example, I have shock ready but when things are thrown my way I can't switch fast enough to get to my telekinesis before the missile hits my face.

You can access the weapon/plasmid selection menu by pressing TAB. I don't personally use it because it's immersion breaking. :)

The TAB gives me something like a script thing I can type in or something.

That's odd - the menu should be like this:

Have you checked the key configurations?

Are you talking about Bioshock 1? I'm talking about 2.

Yeah, I was talking about BS1. In BS2, there is a weapon wheel only in the console version (or if you play with a controller on PC).

that's ridiculous. The weapons wheel would've made things so much better in Bioshock 2. Does this game have mod support?
