Killer Concept: The Hunter (Left 4 Dead)
I'm not good at making perk icons so... just imagine some cool icons in their place.
Edit:
Photophobia now persists for 15 seconds after being blinded instead of acting similarly to Mother's Helpers (I originally intended Photophobia to be kinda useless but I don't want BHVR getting any bad ideas)
Mania now reduces Bloodlust progress when breaking a pallet instead of not resetting Bloodlust at all. It's still really good, but now a significant chunk of Bloodlust progress will be lost, giving some sort of way for Survivors to at least slow you down.

Comments
Mania should increase the chase time required to bloodlust is exchange for being able to break pallets without losing it.
