Frictional Games' own game engine goes under the name HPL and uses industry standard technologies such as OpenGL, OpenAL and Newton Game Dynamics. The engine was released to the public as open-source in 2010 after the Humble Indie Bundle promotion finished.

Authors about the engine:
"The engine is built from an engine created when making a thesis job which resulted in the platform game Energetic. Before moving into the 3rd dimension I made some cleanup of the engine (which was quite rushed in some places) and started to add a base for 3D rendering. I would not say that the original 2D engine was modified to add 3D, but rather a 3D layer was added so all of the 2D stuff is still there. It is still possible to make a 2D tile game using our engine."

It's a very nice engine, performed better with interaction than Oblivion does. Also I loved the Penumbra games, can't wait to see what their newest engine can do.

And yet I doubt anyone will use such a fantastic Engine that has a eerie sense of reality.
