Frictional Games is a small games developer located in the south of Sweden, more specifically in the town of Helsingborg. We develop our own technology to power our games, so far we have released three titles - all part of the Penumbra Series. Frictional Games isn't really located in Helsingborg, two of us live here and the company is registered here, other than that it is very much a virtual company. Currently we are five people working full-time, all from our own homes, with the Internet as our "office". In addition we hire contractors to help out with specific tasks during production, such as audio, writing and graphics. Our own game engine goes under the name HPL and uses industry standard technologies such as OpenGL, OpenAL and Newton Game Dynamics. The engine is currently undergoing an extensive update and the new version is cleverly named HPL2. HPL2 is being used in our upcoming game, Amnesia: The Dark Descent.
