Dark Driver is a VR driving adventure game.
This proof of concept was created mainly to test the unique art style of Dark Driver. Only lights sources and things that are illuminated from within, such as windows and signs, are visible through the darkness.
Your headlights will illuminate the road in front of you, more so than shown in these videos. Other objects that would be illuminated externally will generally not be shown, though there may be exceptions.
The use of simple assets to create a large game world allows the game to run at a high frame rate on modest equipment, and makes world building relatively easy.
