This is an old thing I worked on in 2014/2015. I didn't really know what I was doing and I don't plan on finishing it. However some people have told me to release it, so here it is. It obviously requires Half-Life: Source to run, and you install it as a regular Source mod.

Gman Invasion in source?... Sounds Interesting (¬‿¬)
