This is the Descent 3 open source engine, licensed under [GPL-3.0](https://github.com/DescentDevelopers/Descent3?tab=GPL-3.0-1-ov-file). 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](https://github.com/DescentDevelopers/Descent3/actions) tab.
The milestone needs testing on all platforms. Please report issues when found.
## Usage
Purchase Descent 3 from a reputable source, such as [GOG](https://www.gog.com/game/descent_3_expansion) or [Steam](https://store.steampowered.com/app/273590/Descent_3/), 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
If still using the Descent 3 launcher, copy your `Descent3.exe` binary to your install folder and rename it `main.exe` (back up your old one). Otherwise, drop in `Descent3.exe` and play!
#### 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.
## Building
