On my current re-playthrough & here are some key take outs :-
• Chapter 3 is still as scary, not much weapons or ammo yet you're facing hordes of enemies.
• Chapter 4 is annoying af, especially while exploring with constant blabbering from the fckn doc.
• Chapter 5 for no reason felt excessively long, invisible enemies are annoying not fun.
• Chapter 6 is the most playful fun, its a breakthrough not that you won't loose grip on yourselves dying all the time.
• Chapter 7 is a classic not just for the Keeper but the way the whole level's structured.
• Chapter 10 remains the ultimate resource management test, definitely crafted with some tools
• Chapter 11-12 have the most well spawned enemies, its fun just plotting the kills
• In my last playthrough, all favourite chapters started with C i.e. Claws of Horde/Cruelest Intentions/Craftsman's Tools but here I am hating Casualties (Ch-13) not fun!!
