Here I have some screenshots of part of a level for Left 4 Dead I am currently working on. The level starts with the survivors on top of a motel. They wil have to leave the roof and make their way past the rooms and down into the parking lot. They will then need to avoid the car with the alarm, so they do not alert the horde, and cross the street and go through a series of alleyways to the saferoom.

The blockout for the motel and some of the surrounding buildings is done; I have moved to texturing and a first pass of placing props. A basic enviroment light is lighting the scene. Some screenshots have a different skybox and feature a directional light.
