A few of us from the Nexus staff made the trip out to see id Software's Doom 3 running live. The build on display was clearly a vertical slice rather than anything close to final, but the engine work is already the main story.

The lighting model is the part that is hard to describe to someone who has not seen it. Every light casts real-time shadows, and the UAC corridors we walked through felt unsettling because the darkness is doing the work, not scripted jump scares.
