This scene was based off a concept that i found on the internet. All models were done in 3D Studio Max. High Poly sculpting was done in Autodesk Mudbox 2012. Texturing was done in Photoshop CS4 and Mudbox 2012. Final model placement and post process effects were done in UDK.

This first image is the scene in UDK unlit:

This next image is the scene in UDK lit:

The finalized scene is with fog and post process 
effects including bloom and depth of field:

This image shows each model used in the scene, the texture maps used and the poly/vert count of each object. All texture maps are at 2048 x 2048 resolution:

These images show just a few of the high poly models I did in Mudbox 2012 for the creepy hallway scene in UDK: 

This is the high poly floor model. I sculpted the model to 

reflect aging metal as it bends and warps 

under stress, heat and age

.

The same techniques I used for the floor model
were applied to the wall model as well.

I wanted to make the wall look more weathered/ruined
due to damage and fighting
that occurred in the hallway.

This image is what I used for the initial concept:
