The level we saw started off in downtown LA. It was nighttime (naturally) and the main character took to the streets. Everywhere we looked, there was impressive lighting and shadow effects at work. The Source engine does a marvelous job rendering both outdoor and indoor areas. Certain indoor sections, for example, demonstrated complex geometry and detailed texture patterns, but even with all that, the game ran smoothly and was a pleasure to watch. An impressive level of detail was shown in a nightclub called Confessions, the best place for hanging out if you're a vampire wandering through the streets of LA. Almost every object was modeled in 3D and can be manipulated with.
