Change KActor physics
I am trying to make a level that works similar to this video: http://www.youtube.com/watch?v=eQMBGLMtdFE
Right now I'm doing this with a bunch of KActors stacked on top of each other. However, once one of them is shot the whole tower comes crumbling down. Is there any way to get this sort of physics in UDK?
So you'll need to set all their physics to Phys_None initially. Then on a touch/take damage event change their physics state to Phys_Falling. If you're going to be adding a lot of actors like this, you'll want to make an Unrealscript class for them. Kismet will get extremely unwieldy with a couple hundred of them.
