IGN Games have scored videos from the XBox version of NightFire which has been previewed at E3 in Los Angeles.
There are three different videos of different segments in the game. They are called "Skydiving cut-scene", "Pretty Girl" and "Awesome Footage". IGN has noted that the game has a long way to go before it is complete in terms of polish and graphics, however, "it's already looking great, sporting a huge draw distance, high-res textures, and a slick framrate of 60".
