- Can I go 'prone'?
You can crouch, but I didn't see the player going prone.
- Will there be trees and water, for example, that I could place when I'm in an outdoors environment?
Don't know if those kind of models will be included but if not then you can do this yourself.
- Any chance of having a left-hander's look (the gun on the left side of the screen)? If it would be easy to accomplish this, it would be great. I really want this one more than anything.
Dunno. Didn't see it in there.
- I imagine that it would be configurable, too, but I would like to know that I won't be stuck with WASD keys (which apparently people use a lot in the FPS games).
I believe that keys are configurable.
- Sorry if this seems silly, but: can I have a basement level? For example...I go into a building, which is the first floor. Will I be able to have it so that I can go down from there to a basement or even further-down areas deep underground?
Yes. Either within the same loaded level, or advancement to another loaded level. Basically, each level can have multiple floors.
Did that help?
