So I started playing Bioshock again due to the sheer disapointment brought on by the sequel and I noticed nobody had done this before. I think Bioshocks best weapon is the Wrench. It requires quite a lot of tonics to reach its full potential but once you get those tonics there's nothing it can't do. It can kill hard, fast and silentily, freeze enemies, restore health and eve and with a few more tonics you can turn invisible when standing still and send out an electric shot whenever you are hit by an enemy. What's your favourite.
