The flashlight is present in both single-player and multiplayer modes. It serves as an exploration tool that realistically cuts through shadows, and it also serves as a last-ditch-effort melee weapon. But if you have your flashlight in hand, you don't have any kind of decent weapon equipped. This point was driven home by the sudden appearance of another zombie, who leaped from the shadows of the heretofore strangely quiet hallway. As we dodged away from it, we watched as it lunged for us and closed its arms around thin air in a failed attempt to grab us before we blasted it. We also came to a short stairway. At the top of the stairs was a heavyset zombie who noted our presence. He then grabbed a nearby barrel and hurled it at us. We dodged the barrel, but it tumbled off to the side, and the sound of it crashing to the ground reverberated realistically around us.Also, IGN quotes unnamed sources in reporting that "progressive metal band Tool is doing an original song for Doom 3." Update: There is yet another DOOM 3 preview on Eurogamer (thanks Frans).
