It is a symmetrical map with a looking post in the middle. The buildings are wooden and the walls are concrete. Fast-paced and fierce firefights are commonplace as the map is no larger than Shipment. Shotguns and submachine guns work particularly well on this map, as well as some assault rifles.
If the player jumps off the looking post and lands in the red circle, they will not suffer any fall damage.
If the player looks outside the building in spectator mode, it is possible to see that there are two more similar buildings, on either side.
In spectator mode, if the player goes up through the roof, they can go through the window of one of the adjacent buildings and go inside.
In Call of Duty: Modern Warfare: Mobilized, there is a multiplayer map called "Killhouse" as well. It is almost a replica of the console version. However there is no platform in the middle, and the player can climb up a ladder and walk around the edge of the walls.
Throughout the map, there are a few allusions to the story of the game, including Captain Price's hat on a table, and Khaled Al-Asad's cap on a folding chair.
In Call of Duty: Warzone, there appears to be a reference to Killhouse situated somewhere near the Arklov Peak Military Base in the Verdansk map. The location's appearance isn't a warehouse like the original, and the tower is situated outside the 'house'. The layout however remains almost the same.
