Yeah, that's pretty much all they did. I do agree though, Darkness is a fucking sick game. I haven't beaten it yet, but that's because I only rented it. I plan on buying it soon though. It's a shame that the multiplayer never ended up working out. It could have been a lot of fun.
Yeah, it sort of pissed me off how they turned it into a sci-fi game. Screaming and blowing up heads? No thanks. However, I thought the multiplayer was phenomenal. I got the kills achievement within like less than a week. I was addicted to it. It's a shame no one plays it anymore.
I kinda see what you mean about Condemned 2 not being as good. I would almost say the fighting is better but it's just that. They made it too complicated. Although it creeps me out a little more, I don't have the urge to play like I did with the first.
