This is an indoor map set in part of the Atmosphere Processor which featured in the film Aliens as the squad first make a descent towards the colonists.
As with other DLC maps like Bug Hunt and Reconnaissance, areas and layouts are different from story lines in the singleplayer campaigns and from the Alien films, like in Processor which only features two levels of the Atmosphere Processor.
In this level as in a few others a Xeno Boiler and Xeno Crusher can be awakened, these Aliens can be selected and chosen in gameplay as a highlighted Xeno usually appearing in an area not accessed by marines.
A multiple level map with the APC from the film left in the central area, levels lead away descending towards the cooling pipes and heat exchangers in a hive area and up on gantries that surround the central area.
