To play Descent and Descent 2 over DXX-Rebirth you still need the content of the original games, since it was not released together with the Sourcecode. The game content consists of the game missions, textures, models, sound and music – in short: everything that you can see or hear inside the game.
If you have an original copy of the game(s) (full version, OEM, Shareware, whatever), you can use it with DXX-Rebirth – no problem. Each individual package will explain in detail how to set it up properly.
If you do not have a copy, yet, then you might want to check out GOG! GOG offers many PC-games as cheap and completely DRM-free downloads. Descent and Descent 2 are also a part of their huge catalogue. Buying there will also give you access to special content and extras provided by GOG and their games work flawlessly with DXX-Rebirth!
Descent 1 and 2 are awesome games. And I know many will agree with me. But if you are new to the experience, you might want to try before buying.
No problem! Here you can download the Descent Shareware content as well as the Descent 2 Interactive Demo content files as well.
[DOWNLOAD] “Descent – PC Shareware” game content
[DOWNLOAD] “Descent – Mac Demo” game content (NOTE: The Mac Demo content does not contain any sound effects. To fix this issue, add this Addon to your game installation.)
[DOWNLOAD] “Descent 2 – PC Interactive Demo” game content
Note: These packages only contain the actual game content, which will work with D1X-Rebirth and D2X-Rebirth. However they do not contain the original engine (EXE-files) so it cannot be used as a standalone product.
These packages can also be used for distribution of DXX-Rebirth on game compilations or Linux distributions. Feel free to use them, but if it’s not to much to ask, let me know.
