/vr/ - Retro Games

I stopped working on my doom mod for a while because I ran out of ideas, the first level is a village, the second one is a church that leads to sorta of a hell outpost that teleports you to the third stage, and I have no idea of what to do on this third stage. I kinda want to do some kinda like a castle assault type of thing but I am not sure what to do

I have been playing heretic for some inspiration but I am not exactly sure of what I want to do
