DunGen allows you to procedurally generate a dungeon layout by piecing together hand-made rooms using a configurable set of rules.
This method provides all the benefits of a procedurally generated environment while giving you a lot of control over the end result and it avoids the common pitfall of proceudral content looking bland and obviously computer-generated.

Includes a simple top-down dungeon crawler sample project (Sample requires Unity 2019.1+)
