    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).

    episodic/maps/personal/doug/traintest3.vmf

    episodic/maps/personal/gautam/proto_snow_01.vmf

    An arctic-themed map. Nothing interesting.

    episodic/maps/personal/gautam/styleguide_ravenholm_01.vmf

    This map appears to be from the cancelled Half-Life 2 episode which was being developed by Junction Point Studios in late 2005. It takes place in a snow-themed version of Ravenholm which includes small puzzles, scripted sequences, and fights. This game is not related to Arkane Studios' cancelled Episode Four, also known as Return to Ravenholm, which would have also take place in the town.

    It is implied that the player crashes into a warehouse in a gondola. He wakes up in a room with two unique characters named Duncan and Scooter. There is a train station and buildings nearby. A group of rebels and Combine Soldiers fight on the streets.

    > Duncan (ravenholm_npc_mueller) and Scooter (ravenholm_npc_scooter) are unique entities. Duncan uses a generic Citizen model, while Scooter's model is unknown.
    > Some entities use JPS as their prefix in their names, which obviously stands for the studio's name. In addition to this, some objects have fields called magnet and magnetization, which are related to the Magnet Gun mentioned by Warren Spector in the interviews.
