Welcome to the Neighborhood!

Bad Neighborhood is a custom-built four-part campaign for Left 4 Dead 2, A multiplayer survival FPS horror video game developed by Valve. (Gameplay shown below in the first video)

In Bad Neighborhood players must fight their way through a suburban street, a school that the military used as an evacuation point, an old underground sewer system, and a park that has all been overrun by a zombie outbreak.

The images shown below will walk you through the design and the breakdown of the features implemented in all four levels on the campaign.

Bad Neighborhood was created using the Hammer world editor(Valve's Source Engine Tools), photoshop, and Nem's Tools for the Source Engine.
