Breach charges to save time walking to the heavy doors AND preserve Killing Spree to ensure the shots pierce both enemies and hostages. Extra gear was used to start with an extra breach charge. The route avoids a spawn trigger that skips 2 knife guys coming out of the orange door and ends in the slow-motion room to save a second having to exit.

Edit by Wavuvi: Milliseconds set to 999 for a newer record with milliseconds to be the competitive 1st place.
