This is where we have left it, for a while now. It is a pretty complete overhaul over the prior release, but I felt like it deserved a full release. It is missing many features to be considered complete, so don't expect it to have everything.
Either install the source code zip - see the installation page on our readme (recommended option), or download the binary zip.
A presets.json file is included in the root directory of the folder. You can use this to see what weapons we were testing across builds.
