They took a huge gamble with this one, obviously a departure from their previous installments but for the most part works for me. Gameplay is more slower and the atmosphere is much creepier but ID Games thought out how this would play out and made the correct changes to reflect these changes.

Does get a bit tedious, especially how every time you hear/see enemies spawning, it becomes second nature to turn around as 99% of the time they will generate several enemies from behind to kettle you in in replacement of actual difficulty.
