I did a street corner in an urban setting. It would be used in a first person shooter. Buildings, brick walls, and barbed-wire fences would help contain the player in the scene. The player would start at one end of the road and work to the other side of the street fighting enemies along the way. The player could find cover behind walls, broken down cars, etc. Its kind of a rough draft but it gets the idea across.
This is the top-down view of the street corner I made. You can see a tank in the park and the top of a parachute floating down.Here is a side view of the scene. You can see the parachuter is about to touch down.
Here is another side view of the scene facing down the other street where you can see a broken down Camaro next to a store.
This is a perspective of the entire street corner showing all the details.
