Level Design in UDK: Work in Progress 2 - Toggable Lights and Damage Areas, Spawning Explosions and Rigid Bodies, Elevator, Using a Flashlight and Ladders

This work in progress video shows the player attempting to use a door which malfunctions.  The explosion cuts out the electricity and creates an electrical damage area.

The player takes an elevator down a level and finds a flashlight.  The elevator controls are damages on this level as well.

Another doorway leads to a ladder.  At the bottom of the latter, the player will eventually be able to fix the electrical problem and get back on track.
