Level 0.03 Post-Apocalyiptic Rooms

Level 0.03 or better known as Post-Apocalyptic Rooms used to be the main retail store of the Backrooms but over time it deteriorated and was abandoned. The store covers approximately 300 Km2. The atmosphere of Level 0.03 is yellow and this is due to the presence of nitrogen dioxide (NO2). The nitrogen dioxide has led to the gradual deterioration of the level as a result of the acidification caused by the interaction between water and nitrogen dioxide to form nitric (HNO3) and nitrous (HNO2) acids.
