The map's subtitle on the intermission screen is Seal off med-labs. In automap mode, the title is given as E2M3: Med-Labs.

Letters in italics refer to marked spots on the map. Sector, thing, and linedef numbers in boldface are secrets which count toward the end-of-level tally.


Other points of interest[edit]

It is virtually impossible to get 100% kills in this map due to a shortage of ammo. 100% kills is not, however, the intention, with the aim of the map being to seal off various areas in order to keep the monsters at bay.


There are no official secrets in this level.


According to Justin Fisher, this level is one of two extreme cases where he exceeded the two-sided linedef limit in Doom v1.2. When viewed from a distance, the outdoor area can induce a large HOM.
