What it says on the tin: Doom 64 weapons remade for Doom 2
Grab the pk3 file from the Releases and drag 'n' drop on your source port! I built this mod with GZDoom and while I did my best to avoid ZDoom/GZDoom proprietary functions and such, I haven't tested that it works on other ports, so your mileage with them may vary.
Just zip the source code and change the file extension from .zip
to .pk3
and drag 'n' drop!
