HPL2

Welcome to the HPL2 documentation hub. Here you can find documentation about the different versions of the engine.
HPL2 was used to create Amnesia: The Dark Descent, and an upgraded version of the engine nicknamed HPL2.5 was used to create Amnesia: A Machine For Pigs.

Because the Machine for Pigs version is in majority identical to the The Dark Descent version, most of the documentation resides in the latter.
