HPL1

Welcome to the HPL1 documentation hub.
Here you can find extensive documentation about the engine, including downloads for various tools and tutorials on how to create your own mods.

Warning: It's difficult to do anything with Penumbra: Overture and Penumbra: Black Plague as it requires using old software and learning a great deal before anything useful can be made. Take the time to read through the documentation and familiarize yourself with the tools.

Overture and Black plague are identical scripting-wise but differ with enemy types. Black Plague introduced the infected character whereas Overture can't load those in-game.
