I just got to the Dead City map for the first time in any STALKER game. On the one hand, I love the feeling when you walk in a map you've never played before, armed to the teeth and prepared for everything and anything. On the other hand... Controllers. Lots of Controllers.
I can deal with Bloodsuckers every other day of the week, but Controllers just freak me out. I remember almost quitting halfway through my second playthrough of Clear Sky because I knew that I had to fight one of those freaks in the Agroprom catacombs.
