Frictional Games is an independent video game company. The developer comprises a small core team, and is led by Thomas Grip and Jens Nilsson. Certain key roles, such as Music and Narrative Design, are performed by external staff like Mikko Tarmia and Tom Jubert, respectively. Linux and Mac OS X ports are handled by Edward Rudd.
The studio's first commercially released video game was the survival horror game Penumbra: Overture in 2007, followed by its sequel Penumbra: Black Plague in 2008 and finally the expansion, Penumbra: Requiem later in 2008.
All of Frictional's titles employ the in-house game engine, HPL. Penumbra itself was originally a tech demo created in 2006 to show off the technology.
Based in Helsingborg, Sweden.
