FFracer is an independent racing video game. It has been created using footage from the Bergensbanen documentary showing every minute of the scenic train ride between Bergen on the Norwegian west coast, crossing the mountains to the capital of Oslo".
The game's concept was to take a popular documentary of Norway's picturesque landscape and let people experience it in an interactive way. Players can coast through the Scandinavian forests, snow-clad mountainside, and glimpse at the colorful cabins with music and accelerating speed.
The game includes 17 tracks that correspond to the 17 train stops between Bergen and Oslo. The player must complete each track before the time runs out by avoiding crashes and going at full speed. There is no maximum speed -- the train accelerates as long as the player makes turns correctly.read more
