I was pretty amazed even though I only see gameplay and trailers in Youtube. I guess that It would be a challenge fighting multiple enemies with a flashlight.
The original announcement for it was 2005, there was even talk of making it an open world game.
Bizongod, you do have normal guns in it, however you need to use flashlights, flares, lamps, ect, to illumiante the enemies in order to cause them damage.
