In a way, chainsaw dude is the hardest part of the game (just because you're so underpowered at that point, and not yet used to the combat). It's certainly not an easy game, but I found him harder than anything that came since.
It was so satisfying to fight him again on NG+ and wreck his shit using stealth kills.
@shagge: "It's not about being able to see, it's about feeling normal."
I just wanted to say to him:
"That's great, asshole, but did you see my body parts crumble and fall apart like Isaac Clarke when that fucking dog slammed into me? Now go back and get my bladder hanging off that branch. It's not about being able to pee, it's about FEELING NORMAL. Dick."
@yummylee Oh man, that's a shame. I was hoping to NG+ it on whatever the third, unlockable difficulty is.
