Bioshock

I am trying to finish Bioshock before the Orange box gets here from Amazon. This is fairly hard because most of my time is taken up with school work. I am pretty far into the game I think, I am about to get the next portion of the potion so that I can get rid of the somewhat annoying "unstable plasmids", when the game randomly changes your current weapon to a random plasmid. I need to get back to playing it now!
