Descent 3 by Outrage Entertainment

This is the Descent 3 open source engine, licensed under GPL-3.0. It includes the '1.5' patch written by Kevin Bentley and Jeff Slutter several years ago and brought to a stable condition by the Descent community.

In order to use this, you must provide your own game files. See the Usage section for details.

Version 1.5 Notes

There is no "release" yet. The current milestone is "1.5 Stable", which is meant to more or less be Descent 3 as it might have been if the 1.5 patch had made it to retail years ago. Artifacts can be downloaded from the Actions tab. The milestone needs testing on all platforms. Please report issues when found.

Usage

Purchase Descent 3 from a reputable source and install it, then replace the main binary with the newly built Descent3 binary under ${CMAKE_BINARY_DIR}/Descent3/*/Descent3[.exe]. See your platform below:

Windows

In the install folder, rename main.exe to main.old and take your built Descent3.exe, name it main.exe, and add it to the install folder.

MacOS

Right-click Descent3.app, click Show Package Contents. Back up your Descent3 binary and drop your built Descent3 binary into the install (Contents/MacOS) folder.

Linux

Back up your Descent3 binary and drop your built Descent3 binary into the install folder.
