I was playing this all night as well. Somehow I find it more funny than scary though, since the hybrids really act strangely at times and are sometimes paying more attention to their incessant mumbling instead of attacking you. :D ("we are, we are, we are... aaahh!" :D) I have been using the wrench on just about everything so far; it has to be the best overall weapon in the game. Also, regarding the protocol droids, the manual says that they are supposed to be "unarmed and always helpful," but why do they run into you and explode in the game? :p
There was this one really confusing part later on though. When you step into the Engineering B area, the view suddenly shifts and there are these two guys in a cave talking about some weird thing. It is difficult to make out what they are saying though.
