Play as a cultist trying to thwart the combine and replace them with his own Deity. Shoot combine, Explore relatively interesting areas and try not to die. I hope you'll have fun
My honest opinion about this is it's a good start. It's a solid start. I was really confused about a lot of stuff, but overall I think with some tweaking, this could be a really great mod
Fun creative mod, with a couple of completely game-breaking bugs. Worth a download.
