Original Game Data
==================

In order to play this game you need original game data.
Unless you have original Descent CD (or shareware episode) you can get
DRM-free version of Descent from Good Old Games (GOG.com):

    https://www.gog.com/en/game/descent

The package game-data-packager(6) supports Descent to create convenience,
easy installable data packages and should also be able to update the data
automatically to the latest version.

For example, you can create your game data package with:
   game-data-packager -i descent1 <path/to/gog.com_installer>


Or you can do a manual installation, and extract game data files using
"innoextract (>= 1.3)" utility :
The following files will need to be placed to "~/.d1x-rebirth":
    DESCENT.HOG
    DESCENT.PIG

Optional multiplayer missions can be copied to
"~/.d1x-rebirth/missions":
    CHAOS.HOG
    CHAOS.MSN
