On March 24, 2017, an unknown individual leaked the original map files for the Half-Life 2 episodes. These uncompiled source files show us the different development stages of the games. For today's article, we examined these files and wrote a description for each map.
The first part of the article covers the maps from the "episodic" folder, which consists of Episode One maps but also include several early Episode Two prototype maps and a map from the cancelled Half-Life 2 episode which was being developed by Junction Point Studios (see "styleguide_ravenholm_01" below).
