These generation methods are designed to have way more added to them, this is only the beginning of what they can do.
The first kind of procedural generation developed for Shadow Survival was the wilderness level generation, suitable to terrains like deserts, swamps, jungles, etc.
Then I worked on the city street Procedural Generation.
And then came the underground base generation, for now is basic, but will have countless possibilities added.
Will do another article about the Procedural Generation after I quadruple the possibilities.
