Last week at GDC, Epic Games showed off a new version of the Unreal Engine 3 that boasted a ton of new features.  To showcase this, they created a demo called "The Samaritan."  In a look and setting that clearly looks inspired from Bladerunner, we see a rainy futuristic city with neon lights reflected in every puddle.  A man on a rooftop witnesses a beating and jumps in to help out.
