yah it does change

And yeah, I was confused at how a few parts would work, but none the less, they do
EDIT: Bioshock - the missing plasmids.
Read and wonder
I wonder how these 'pressure plasmids' would have worked?
Also
This video shows some stuff that doesn't seem to be in the game any more
The teleportation plasmid, the ability to lean around corners and a little sister drinking adam, the Big Daddy's lens is blue the rage plasmid is a gooey stress ball of some sort too.
Kinda sucks that the game didn't end up more like this video. I mean, except for the fact that the player obviously has an infinite health situation going on, it makes the big daddy fights look like more than just the wrench fest I found them to be. Plus, once you've got the upgraded shotty or the chemical weap, there's just no challenge even on hard mode.
Still.
