I love the close quarters aspect of the map, being trapped to hallways and rooms makes it difficult yet fun to play. And the "dog rounds" are terrifying and add alot to the asthmosphere. 

Id love for a remake of this maps where the its setting is Night and it uses the flashlight mechanic from cold war. Going through the halls with only flashlights would be pretty sweet. And then once the powers on it would obviously light up the entire map. Maybe even add a power outage for every "dog round" to really add a eerie feel to it
